In the last two posts I discussed aspects of services in the context of some landscaping work that I’m having done. This is clearly what many people would call a “non-IT example.” I often use similar examples in my classes. However, I might initially describe an example that seems unrelated to IT, but will conclude with a challenge to students. That challenge is, “identify the IT in this example.” The truth of the matter is that most businesses these days are underpinned by some form of information technology. In fact, technology has become so ingrained into everyday services that often even the service providers themselves don’t realize how technology supports their business.

Knowledge Management examines how we acquire, organize, manage, share, and utilize knowledge and information. The Internet gives us an overwhelming amount of information on a daily basis — and the volume of information available is growing rapidly! One of the biggest challenges for individuals and organizations involved in project management is to make the best use of this knowledge and information so they can operate more efficiently, improve decision making, and sustain a competitive advantage.

As we discussed previously, Cisco created the Nexus Operating System (NX-OS) to power its next-generation data-center switching platform. While this new OS shares many similarities to the original IOS, there are some definite differences that you need to be aware of as you begin using it.

Some of you might just be starting out as a database administrator and need to know what a basic Transact-SQL query is for Microsoft SQL Server 2012, others might already be creating database objects. Either way, we put together a list of a few terms regarding Microsoft SQL Server that any database administrator should know.

That depends on their configurations. For example: While it makes very good sense to include redundant physical links in a network, connecting switches in loops, without taking the appropriate measures, will cause havoc on a network. Without the correct measures, a switch floods broadcast frames out all of its ports, causing serious problems for the network devices. The main problem is a broadcast storm where broadcast frames are flooded through every switch until all available bandwidth is used and all network devices have more inbound frames than they can process.

Now that the network is installed, each switch has a bridge ID number, and the root switch has been elected, the next step is for each switch to perform a calculation to determine the best link to the root switch. Each switch will do this by comparing the path cost for each link based on the speed. For paths that go through one or more other switches, the link costs are added. The switch compares this aggregate value to the other link costs to determine the best path to the root switch.

For several years, most news articles about a computer, network, or Internet-based compromise have mentioned the phrase "zero day exploit" or "zero day attack," but rarely do these articles define what this is. A zero day exploit is any attack that was previously unknown to the target or security experts in general. Many believe that the term refers to attacks that were just released into the wild or developed by hackers in the current calendar day. This is generally not the case. The "zero day" component of the term refers to the lack of prior knowledge about the attack, highlighting the idea that the victim has zero day's notice of an attack. The main feature of a zero day attack is that since it is an unknown attack, there are no specific defenses or filters for it. Thus, a wide number of targets are vulnerable to the exploit.

Self-awareness is a very powerful tool for leaders in every type of business or organization. The more leaders can maximize their self awareness the greater the impact on business performance, employee engagement and leadership and development initiatives. Self-awareness is the central component of personal development and emotional intelligence. For most leaders today it is still underdeveloped and frequently underemployed. Better understanding of this important leadership trait is critical for leadership and organizational success.

We already covered the first three of the twelve advantages of Agile software development. These three advantages focus on team development and refining the process. Advantage #4: Motivated Development Team The positive relationship with a reasonable and satisfied customer is only one of the reasons why many developers prefer to work on Agile projects. The other main contributor is that they tend to value working in self directed teams (which the Agile methods require for success).

Depending on the switch vendor, the exact steps will vary on how to set up and configure VLANs on a switch. For the network design shown, the general process for setting up VLANs on the switch is:

If you are upgrading to ESXi 5.1, there are some important facts that you should consider first. Upgrading involves many stages and processes that must be performed in a specific order. Many of these processes are one-way and do not provide a "back button." If you do not use care and consideration in your upgrade plan, you could possibly lose important data and configuration; and potentially even lose contact with your servers.

In 1998, the Internet Engineering Task Force (IETF) released RFC 2460, outlining the technical specifications of IPv6, which addressed the shortcomings of the aging IPv4 protocol. As with any evolution of technology, new elements exist in the protocol that may seem strange and unfamiliar. This certainly includes address representation, space, and so forth, but also includes a number of different types of addresses as well. A subset of these new addressing types has corresponding types in IPv4, but many will seem significantly different. The purpose of this white paper is to examine addressing classifications in detail and outline their functions within the context of the protocol.

ITIL describes a service portfolio as a collection of the overall set of services managed by a service provider. A service portfolio describes a service provider’s boundaries and promises across all of the customers and market spaces it serves. I like to think of a service portfolio as describing the past, present, and future collection of services offered by a service provider. The figure below shows a high-level view of a service portfolio.

In a recent post, I gave an overall description of a service portfolio and the key components of a portfolio. Here, I will describe how a cloud services provider might implement an ITIL service portfolio. A cloud services provider will regularly have a set of services under development, a set of service in live operation, and a set of services that are retired.

The STP (Spanning Tree Protocol) standard (IEEE 802.1d) was designed when the recovery after an outage could wait a minute or so and be acceptable performance. With Layer 3 switching in LANs, switching began to compete with routers running protocols because they are able to offer faster alternate paths. Rapid Spanning Tree Protocol (RSTP or IEEE 802.1w) brought the ability to take the twenty seconds of waiting for the Max Age counter plus fifteen seconds of Listening plus fifteen seconds of Learning or fifty seconds down to less than one second for point-to-point connected and edge switches and six seconds for root switches.

As with the adoption of any new technology, the move from IP version 4 to IP version 6 will take a number of years to complete. During that transition phase, various mechanisms will be necessary to continue support of the older protocol as the newer gains widespread momentum. In addition, there has been some evolution even within the availability of these mechanisms, some of which have already passed from general use into deprecated status. Network engineering professionals already proficient in the use of IPv6, as well as the available coexistence mechanisms, will undoubtedly stay in high demand throughout this process.

Risk is something we deal with on a daily basis. Living in New Jersey and having the occasional storm, I’ve recently performed my own risk assessment determining the value of certain assets and activities and made a decision on what I was willing to spend to reduce risk to what I perceived as an acceptable level. My management of risk was a rather simple case. Sure, in my revised business continuity plan for my home, I’ll make sure that I have more D cell batteries, have my garage door adjusted so it opens manually again, more food I can heat on a stove and that doesn’t rely on refrigeration, and finally I’ll consider a whole house gas generator that uses natural gas, which has always been available to power critical systems like the sump pump in my basement. What if, however, I was a really large business? One with lots of components and interdependencies that require a tight integration in order to succeed? How and where can a large volume of information necessary to management, business continuity, and disaster recovery be correlated and communicated to those individuals who, because of their roles and responsibilities, need to make the critical decisions regarding the management of risk?

So what makes a new certification "Hot"? Is it the perceived qualitative value? Or is it the possible increase in salary? Is it just the fact that so many are seeking that one particular certification? How about the governing body of the certification? Or maybe it is a combination of one or more of these? Whatever the case, there are new certifications (and some that have been completely re-written as to be a new certification) that are perceived to be the "ones" to possess and will be highly desirable in 2013.

Learning how to program and develop for the Hadoop platform can lead to lucrative new career opportunities in Big Data. But like the problems it solves, the Hadoop framework can be quite complex and challenging. Join Global Knowledge instructor and Technology Consultant Rich Morrow as he leads you through some of the hurdles and pitfalls students encounter on the Hadoop learning path. Building a strong foundation, leveraging online resources, and focusing on the basics with professional training can help neophytes across the Hadoop finish line.

One of the many useful features of tunneling is to carry non-IP traffic across an IP network, and this is still the case when dealing with IPv6 traffic. This transition mechanism makes use of a configured tunnel to transport IPv6 over a native IPv4 network, which may consist of two sites or more. Unlike the previous transition mechanisms, tunneling is not monolithic; while the basic principles may be similar, the operations are different. The following chart gives a breakdown of the current, major tunneling types in use, particularly in a Cisco environment:

This vSphere Essentials white paper will give you a basic understanding of some of the concerns or planning points to consider as you get ready to deploy vSphere in your organization. This is a glimpse into some of the essential things to consider for implementing vSphere. This will focus on some of the basics that vSphere administrators run into when installing the latest features and not realizing they still have some older versions implemented.

Rather than looking back over the past year, organizations and individuals need to start assessing cybersecurity threats that lie ahead in the New Year. While there is always the chance for a new threat or risk to be unearthed this year, often the risks of the New Year are predicable from the trends of attacks from the previous year. However, other factors need to be considered as well, including new technologies, new software and applications, mobility, etc. Here are my predictions of the areas to watch for new security threats. When it comes to cybersecurity, we have a lot to look out for, take precautions against and be paranoid about.

Organizations that plan for and conduct supplier management according to defined processes and boundaries are more likely to receive predictable, high-quality goods and services from their suppliers in a timely manner.

There exists a need to properly read, deploy, and examine the results of Group Policy. By its architecture, Group Policy Deployment to the Clients or Servers can be erratic and latent, or even non-existent throughout your Enterprise Organization, frustrating Administrators who are rolling out the Group Policy to Client or Server computers. To help mitigate this behavior, I compiled these insights into a two part series from real-world examples, experiences, and fixes that have worked for me. I know that these Tips and Tricks will work for you, too.

Rodger Foster, our senior Cisco instructor, reviews how multiple gateways are used to provide redundancy in the network.

Enterprises, whether they are commercial, non-profit, or government entities, are operational organizations that operate through the execution of hundreds of processes. The quality of these processes affects every aspect of the enterprise and these processes are rarely static. Business Process Analysis (BPA) is the discipline of examining processes so that they may be changed to align with enterprise objectives.

This white paper has three main goals. The first is to generate a better understanding of the cloud in both the business and IT communities. The second is to describe the major components of vCloud and the virtual datacenters they provide. The third is help businesses visualize and understand how vClouds could be beneficial in addressing their specific IT needs.

New in Windows Server 2012 is the Unified Remote Access (URA) role. In Windows Server 2008 R2, DirectAccess and Routing and Remote Access Service (RRAS) were two separate roles. In fact, they could not be co-located on the same server. In Windows Server 2012, DirectAccess and RRAS can be co-located, allowing for what is now legacy remote access VPN client connectivity (L2TP/IPsec, PPTP, and SSTP). This means that the Unified Remote Access provides DirectAccess, Remote Access VPN, and site-to-site VPN and can now serve as your complete remote access solution.

Once an organization has categorized suppliers, one of the benefits that is quickly realized is an understanding of how supplier changes affect the buying organization and vice-versa. Changes are the modification, addition, or removal of something from the environment. The scope and scale of each change can be different. Change management covers everything from regular, low-risk, operational modifications all the way to significant organizational strategic shifts.

Cloud forensics involves exploring issues a company and its forensic examiner may face when suffering a breach of company information in the cloud. If they need to collect information from the cloud to determine what happened, to determine what was lost or compromised, for remediation, for civil litigation, or for some other action, what issues will they face? And, how can they collect the data? Although this white paper discusses many legal issues, this is not a legal "how-to" article. The purpose is to provide some insight into cloud forensics.

Resource Pools are often misunderstood, disliked, and untrusted by vSphere Administrators. However, resource pools can be very useful tools for administrators who want to configure resource management without having to individually configure each VM. This leads to the administrator’s desire to explore the proper usage of resource pools.

The OSI model is a conceptual tool used to discuss and describe network functions. The use of a standard reference model is essential to communicate ideas as well as create new technologies. It is a good idea to be familiar with the OSI model, the features assigned to each layer, and examples of common protocols or technologies associated with the OSI layers.

The utility that many senior VMware administrators rely on to address performance and troubleshooting issues is the built-in utility called ESXTOP. The tool has been built in to the hypervisor, and can be used in both ESXi and the old ESX host. The first tool many VMware Administrators rely upon is esxtop, to check real-time performance on an ESXi host using a command-line tool such as ssh to start the esxtop CLI utility. This paper will introduce and demonstrate how to start and use esxtop, specifically looking at the CPU fields. In addition, we will cover information that can be used to help with performance issues of the CPU. The esxtop utility is an excellent tool to use when you want to observe an individual ESXi host's performance.

One of the most important steps in mastering a new technology is learning the associated terminology or vocabulary. In the IT field, this can be a very challenging step, as much of the terminology is often used inconsistently. This white paper defines the terminology associated with IT virtualization. It is mainly vendor-agnostic, but it does provide some vendor-specific terms, product names, and feature names used by VMware, Citrix, and Microsoft.

The OSI model is a conceptual tool used to discuss and describe network functions. The use of a standard reference model is essential to communicating ideas as well as creating new technologies. It is a good idea to be familiar with the OSI model, the features assigned to each layer, and examples of common protocols or technologies associated with the OSI layers.

A local area network (LAN) provides a path of communication, allowing the delivery of packets of data, voice, or video originating from the sender (logical source address) to the receiver (logical destination address). Ethernet is the most common LAN used. As you start to learn about networking, remember that communication and the movement of large numbers, whether it is people, cars, mail, or network traffic, have a commonality. Everything you know and use in your daily life can be compared to the way traffic moves.

Business complexity, technology innovation and a new understanding of how we learn at work are causing the learning profession to re-think how they develop and sustain human performance and behaviour change. As a result new methods and approaches are emerging that promise to change the landscape of learning and development meeting in the coming years. This session will provide an opportunity to learn about the following trends and their application.

This paper proposes a unifying model for project plans. A distinction will be made between the outputs of project planning and the project plan itself. The significance of this distinction is to allow projects of all types to be described at a high level, in a common language, regardless of the type of analysis used to develop the plan.

One of the most difficult concepts for me as I was learning database syntax was joins. Of course, I tried reading and understanding articles and books that dealt with this topic. In almost every case, I was faced with the Venn diagram examples.

ITIL is generally not prescriptive. In reality, the CSI Register at any given organization might look significantly different than the example given in the CSI book. The fields given in this example are important. 

Session Initiation Protocol (SIP) is an internet signaling protocol, developed by the IETF (starting in 1996), for establishing, maintaining, and tearing down sessions between a variety of real-time media, including voice, video, and chat. SIP allows endpoints to locate other endpoints, whether stationary or mobile. SIP doesn't have to worry about transporting voice or video as Real Time Transport Protocol (RTP) takes care of that. It also relies on Session Description Protocol (SDP) to negotiate capabilities and codecs. SIP does not provide a Directory Service or Authentication, but it does work with services such as LDAP or RADIUS. SIP is only concerned with signaling. This white paper is going to look at the way SIP is used in the converged Unified Communications environment.

SOA is all about architecture-after all, it's right there in the acronym-yet most organizations think it is about turning existing software components into web services. When you adopt SOA, remember that it is all about design and governing that design. It's about how you design your service interfaces, your services, your data model, and your business processes. It's about how you keep track of your services, how you control the design, definition, deployment, and distribution of your services and their artifacts, how you define a service contract and service level agreement for your service consumers, how to secure your services, and how to react when things go wrong with them.

While the last few years have brought about many great advances in IT and network technology security and risk management have a critical point. There is a host of new concerns the IT security manager must be concerned with, including social networking, mobile, cloud, and information sharing. This has unleashed a new wave of change and potential risk. Risk management is required to deal with these emerging technologies and should provide the rationale for all information security activities within the organization. You can think of risk management as the process of ensuring that the impact of threats and exploited vulnerabilities is within acceptable limits at an acceptable cost. Risk management requires the use of countermeasures. Countermeasures can include any process that serves to reduce threats or vulnerabilities.

With the growth of bring your own device (BYOD) and mobility, users are increasingly asking for computing anywhere from any device at any time. Users now expect productivity on the go with a desktop that can be freely accessed and secure. We're no longer a society that sits at a desk to be productive. The VMware Horizon Suite allows the datacenter administrators to satisfy the accelerated mobility needs of the workforce while still maintaining an IT solution that is easily managed and secure.

Many I&O leaders and customers see little value from investments in ITIL. Not getting the Return on Investment (ROI) you expect normally comes from using ITIL incorrectly. You, your staff, and your customers must share the same goals and understand exactly what to expect from your ITIL investments. The goal of ITIL is not “business and IT alignment” or “competitive advantage from IT investments.” Instead, its first goal is to stabilize service operation. This builds a base for the second goal: increasing value through service optimization. You must have clear-cut, documented, and managed expectations for each activity, and order is vital. Success requires that you stabilize service delivery before trying to optimize. Focusing on the correct goal and linking each ITIL task to that goal is the correct use of ITIL.

Are you at a crossroads professionally or looking to start training for a new job? If so, you might want to consider pursuing network administration as a career. Network administrators are responsible for maintaining computer hardware and software systems that make up a computer network, including maintaining and monitoring active data networks, converged infrastructure networks, and related network equipment.

Constant change in the technology landscape has been mirrored by the steady evolution of information security. The current information system environment is increasingly complex, comprising storage, servers, LANs/WANs, workstations, Unified Communications, Intranet, and Internet connections.

Traditionally, ITIL and TOGAF professionals have been part of different teams within an organization. Due to the ongoing alignment of business and IT, these professionals now often find themselves on the same team. Because of this crossover, there is a growing trend towards organization of work based on multiple best practice models. 

Now that we have looked at the similarities and differences between the first two steps of the military decision-making process (MDMP) and the project management processes from the planning process group that align with them, it’s time to take a look at the third ste...

VMware vCloud Director fashions the provisioning of the software-defined datacenter layer to allow for a full virtual datacenter deployment within a short period of time. A vCloud consists of many layers and can quickly become a complex architecture. Before any deployment, requirements should be defined so that the vCloud can be designed to offer those services needed. It is imperative to understand the many components of vCloud, how each vCloud construct fits, which allocation models are available, and what network options can be chosen.

In numerous Cisco classes, students learn about IPv4 and IPv6 address subnetting, complex subnetting, variable length subnet masking (VLSM), summarization, prefix routing, and address aggregation. These are valuable skills. In order to apply these skills efficiently, a network designer should possess one additional skill. Planning the IP address space for a Class A or B IPv4 address is necessary to apply the complex skills listed above properly. Complex subnetting, VLSM, and IP address summarization can be implemented simply and efficiently with proper planning.

How can leaders and Human Resources professionals use effective, simple and research-based talent management practices to contribute to their organization's success? Too many leadership development theories provide complex and confusing answers. Join Jocelyn Bérard as he shares the core practices introduced in his new book, Accelerating Leadership Development, which reflects his extensive research and years of experience in making leadership development uncomplicated and practical.

You have spent money on software and hardware, implemented best practices, and believe you are secure, right? You may have overlooked the weakest link: your employee. Many breaches occur as a result of an employee mistakenly clicking on a link or visiting a site that allows a virus to be unknowingly downloaded, giving hackers access to your network. Today, a well-trained workforce is a necessity and may even be your most important cybersecurity tool. In this webinar, security expert David Willson will discuss how many breaches have occurred and are occurring, the tools and techniques hackers use to trick employees into clicking on links or opening attachments, and how to prevent such behavior.

Instructor John Harmon continues his explanation of subnetting by showing how subnet masks can be used to sub-divide networks.

There are several Wireless LAN Standards, including b, g, and n, which exist in the 2.4 GHz band. These standards need around 20 MHz of radio frequency in order to transmit their signals. In this video, Ben Miller discusses how to pick access points and channels for optimal performance.

Business is changing rapidly and Information Technology is at the centre of the trends: mobile, social, cloud and big data,. Forward thinking IT functions must develop and manage the skills of their most critical asset-- their employees. Effective professional development can guard against the pace of change, leading IT units to re-define job roles to include both technical and non-technical competencies and to establish business processes to help their staff develop and maintain these skills. This session will present the components of a holistic process to support learning and development in any IT organization.

vSphere 5.5 is now available with myriad small improvements such as a faster Web Client, LACP, Autoscale and higher configuration maximums. In addition, there are changes coming such as VSAN, which may be ground-breaking in regard to VM storage of the future. Since the release of vSphere 5.5, they have not yet announced a change to the blueprint for the test. That being the case, I will say, for now, that the VCP-510 test should remain unchanged as well. My goal here is not to reeducate you on everything that you need to know for the test; instead, it is to point out the few changes that might apply in your company or organization.

Agile is a set of principles requiring a significant cultural shift, new paradigms in thinking and team organization. Over the years, Agile has become "productized" or in many cases "institutionalized", creating different flavours and levels of commitment among teams and organizations. Along the way, managers and team members have lost sight of Agile's principles and tried to enforce the use of certain tools and structure where they may not belong. In this one hour webinar, Perry McLeod will explain how tools such as use cases can be successful in an agile environment, provided the principles of agile are always active in the minds of the managers and the team members that are using them. Join Perry to determine whether or not making the cultural shift towards the use case method in an agile environment is the right move for you and your organization.
