As far as modern architectures go, there are few more complicated than an IoT pipeline. You’ve got to consider an ingestion layer (typically streaming) that may undergo manic load. You’ve got to think of data tagging, storage (probably across multiple engines), archival and access—both internal and external. And all of it has to scale like crazy, be as cost effective as possible, and use automation wherever it can. Oh, and your boss needs the IoT pipeline built by tomorrow. Short timelines? Tight budget? Unrealistic expectations? Unfortunately, these asks are realities for many cloud professionals. AWS knows this and is here to help.  

Behind various Google services lies the powerful Cloud AI, a neural net-based, machine learning technology that Google has perfected for use with services like image search and voice recognition. Here are five ways you could use Cloud AI to improve your business.

A longtime leader in data analytics, Google continues to earn their position by continually improving their data analytics offerings. Now, with Google Cloud Platform (GCP), you can capture, process, store, and analyze your data in one place, allowing you to change your focus from infrastructure to analytics that informs business decisions. However, you can also use GCP Big Data tools in combination with other cloud-native and open-source solutions to meet your needs. Below is an overview of GCP Big Data Tools and how you might utilize them to improve analytics.

Google takes security to a whole new level thanks to their years of experience as one of the most popular targets on the internet for would-be hackers and denial of service bots. This led Google to build a sophisticated security infrastructure the likes of which few companies or organizations can claim. Google approaches security holistically and involves everything from the physical data centers, to the data pipelines between them, down to the training of each employee that is responsible for managing the infrastructure.

Moving capabilities to a cloud provider such as Microsoft Azure is pretty straightforward. However, given the depth and breadth of service offerings provided by Azure, it’s easy to miss the product’s less obvious capabilities. If you're implementing a Microsoft Azure cloud platform, you'll want to consider these five services to save time, money, and your sanity.

Getting a clear understanding of what Amazon Web Services (AWS) is and how it can help your business can be a daunting task. The depth and breadth of AWS is significant, comprising over 100 services in dozens of data centers located in 16 Regions throughout the globe (with five more in the works). They offer computing, storage, networking, deployment, management, and a host of "supporting" services like queues, serverless functions, and e-mail. There's a great chance that AWS has more than a few products to help you work faster, smarter, and more cost effectively. So, where should you start?

Google Cloud Platform (GCP) is Google’s public cloud offering comparable to Amazon Web Services and Microsoft Azure. The difference is that GCP is built upon Google's massive, cutting-edge infrastructure that handles the traffic and workload of all Google users. There is a wide range of services available in GCP ranging from Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) to completely managed Software-as-a-Service (SaaS). We will discuss the available infrastructure components and how they provide a powerful and flexible foundation on which to build your applications.

Data center return on investment – which is measured by time to cost savings, time to revenue, time to break even, etc. – has proven more elusive than expected. But that doesn’t mean it isn’t attainable. To understand the genesis of the bad and ugly parts of data center ROI, we need to recognize the good parts and appreciate why so many companies are putting their faith in new and unfamiliar technologies.

You might already know what cloud computing is, and you might already be implementing it into your business, but are you able to have a conversation about it? The lingo surrounding this newer technology can be a bit, well, cloudy. Here are just some of the terms we keep hearing as cloud computing spreads from organization to organization.

There is a wide-range of services available in GCP ranging from Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) to completely managed Software-as-a-Service (SaaS). In the first part of this series, we will discuss the available infrastructure components and how they provide a powerful and flexible foundation on which to build your applications.

As with all technologies transforming the way organizations operate, it’s expected that roles will also evolve.

There are many questions you should ask before selecting your PaaS provider. Learn what you need to know in order to compare and contrast PaaS with the other offerings like IaaS and SaaS, and what they require in terms of setup and configuration. As with any decision involving IT infrastructure there are many variables that should be considered to ensure you find a solution that will fit your current and future needs, budget and support requirements.

The advantage—and disadvantage—of IaaS cloud computing is complete control. The user is responsible for sizing, installing, and maintaining operating systems and applications, backing up the systems, etc. This enables the user to configure everything in an optimal way for the workloads that need to be accomplished, but it requires time and effort to determine how it should be set up, secured, etc. With the goal of providing a good place for you to start your IaaS implementation and highlighting some areas that you should plan for and design for, Global Knowledge instructor John Hales provides a review of IaaS, as well as insight into what you need to know before implementing IaaS. He also shares a laundry list of things to consider when implementing IaaS, including questions to ask yourself, your company and your potential cloud provider.

The cloud revolution is truly a revolution - the way we work, learn and even play is very different now than it was just 10 or 15 years and will probably be a lot more different in 10 or 15 years. With this in mind, let's look at 10 ways the cloud will (and to a large degree already has) changed the world.

Change is the order of the day, and if anything, the pace of business and technology change is accelerating. The business and customers are looking to IT service providers to be more responsive, delivering more frequent service changes with higher quality-resulting in services that deliver more value to the business. In order to continue to be relevant and of high value, ITIL must continue to benefit from other complementary best-practices for IT. DevOps, an approach that encourages improved communication, collaboration, and teamwork across development and operations, can have a positive influence in improving ITIL processes across the service life-cycle.

Cloud computing is a big force in IT today, and it isn't going away. In fact, cloud adoption is going up geometrically, both for end users (think apps on your phone or tablet) as well as for organizations of all sizes. In fact, many smaller organizations may not have any on-premises infrastructure at all, other than networking infrastructure to get connected to the cloud. With this transformation in IT, it behooves all of us in the industry to understand it and adapt or risk being out of a job, like punch card operators.

Microsoft Office 365 has a vast array of features to explore. A rich administration interface, streamlined security, and versatile migration options make this one of the most interesting products when it comes to an SaaS public cloud solution.

In this paper, we explore the basic usage of PowerShell in the pursuit of automating the management of Hyper-V deployments. This paper is targeted to IT professionals who have been "GUI-bound" to their management interfaces and have been working with or are embarking on the journey of Hyper-V administration. We'll explore the usage of Hyper-V specific cmdlets with the intent of ultimately being able to include multiple cmdlets in a "script" to allow for pushing one button and accomplishing the combined actions of many multiple mouse clicks in the GUI. No more repetitive tasks!

AWS is an incredibly rich ecosystem of services and tools, some of which have security aspects baked in (like S3 SSE), and others that provide overarching security capabilities (like IAM and VPC) that apply to many services. With regard to data storage, operating system, and applications, security functions largely the same in the cloud or on-premises software. Customers can and should continue to follow best practices that have served them well in their own data centers.

Accessing cloud-based resources, whether they be IaaS/PaaS/SaaS-based, is very convenient. With a browser and Internet connection, you are up and running. No driving to your work office, no need to log into the corporate network. Just open up your web browser and go. This convenience, however, comes with a security risk. All of your business work is conducted over an insecure communication network. Unlike your office network, where the network link between you and the data center is under corporate control and is physically secure, the cloud access link is over the Internet.

Like it or not, Internet of Things (IoT) is upon us. There are a number of factors that will impact its adoption rate, and the inevitable privacy (or lack of) discussions will likely happen sooner than later. This is going to change the world as we know it, in many cases for the better. But we will need to keep an eye on the extent to which it invades our personal lives if it is going to be the positive force it has the potential to be.

Discover how the enhanced performance and reliability of Amazon Aurora will help AWS customers reduce performance bottlenecks in their applications. The relatively low cost of Aurora will tempt many customers to migrate workloads to this implementation of RDS.

Amazon Redshift opens up enterprise data warehouse (EDW) capabilities to even the smallest of businesses, yet its costs, security, and flexibility also make it appealing to the largest of enterprises. It allows companies to easily and conveniently scale their EDW needs both up and down, and as a managed service, it allows your team to offload all of the "undifferentiated heavy lifting" of building and maintaining an EDW. Its raw storage costs are about one-fifth to one-tenth of traditional in-house EDW, and AWS has taken great care to ensure its performance is still competitive with those in-house solutions. Before deciding to use Amazon Redshift, however, it's important to understand what it is and is not.

This white paper explores the native AWS storage solutions, enabling you to deliver applications in the cloud in the most efficient, cost-effective, and secure manner. In terms of storage, it's important to understand the characteristics of each AWS storage option so that you can implement one or more AWS storage services to meet your needs. Often, you'll find that utilizing multiple storage options together will give you the best outcomes.

The National Institute of Standards and Technology (NIST) created a cloud definition that has been well-accepted across the IT industry. NIST was mandated to assist government agencies to adopt cloud computing for their IT operations. As part of their mandate, NIST created multiple working groups to define cloud computing, its architecture, and requirements. In this paper we explore the center core of NIST's cloud definition.

Many people believe that cloud computing requires server (or desktop) virtualization. But does it? We will look at using virtualization without cloud computing, cloud computing without virtualization, and then look at using both together. In each case, we'll look at where each deployment might be most useful, some use cases for it and some limitations.

After a review of Software-Defined Networking (SDN) and its close cousin Network Functions Virtualization (NFV), this white paper addresses three main deployment scenarios: SDN without deploying cloud computing, cloud computing without deploying SDN, and deploying cloud computing in conjunction with SDN. We'll look at use cases, when the approach makes sense, and any applicable limitations.

AWS has introduced Auto Scaling so that you can take advantage of cloud computing without having to incur the costs of adding more personnel or building your own software. You can use Auto Scaling to scale for high availability, to meet increasing system demand, or to control costs by eliminating unneeded capacity. You can also use Auto Scaling to quickly deploy software for massive systems, using testable, scriptable processes to minimize risk and cost of deployment.

Amazon Web Services (AWS) offers increased agility, developer productivity, pay-as-you-go pricing and overall cost savings. But you might wonder where to start, what pitfalls exist and how can you avoid them? How can you best save time and money? Learn what you need to know and where to start before launching an AWS-hosted service.

Database Management Systems (DBMS) have been monolithic structures with their own dedicated hardware, storage arrays, and consoles. Amazon Web Services (AWS) realized that while each company can use unique methods of collecting and using data, the actual processes of building the management infrastructure are almost always the same. AWS remedies DBMS problems with its Amazon Relational Database Service (Amazon RDS).

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.

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.

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.

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:

In the fourth of his five-part series, Eric Strause explores the hardware and application benefits inherent in a cloud-based architecture.

I attended a meeting this week with a customer of mine and a potential new vendor. The new vendor was there to pitch his configuration and setup service offerings for a specific ITSM toolset. My customer has already had one bad experience with an ITSM tool configuration vendor who promised one thing and delivered much less. He ended up with a tool that’s minimally used and not configured to match his business needs. He’s looking for a vendor that can understand his business needs and priorities and quickly help him get his tool configured and working in a short time frame. Then the topic of standard changes came up. My customer asked for examples of standard changes. The vendor responded, “Server reboots are an example of standard changes.”

The flexibility, reduced cost, and mobility of cloud computing have made the concept a hot topic. Before implementing this method of computing, however, it is important to consider the security of the "cloud." In this white paper, you will learn some of the risks and benefits of cloud computing to be sure it is the right solution for you.

The definition of cloud computing depends largely on whether you are a consumer or producer. The public cloud is geared more for the individual consumer or small company, while the private cloud is geared more for a medium-to-large company. In addition, the private cloud is branching out to incorporate the ability to have some data and applications serviced from the public cloud. This white paper examines the different types of cloud computing and shows what cloud computing can offer you.

Microsoft SQL Server has evolved over the years as a scalable, robust database management system and is now competing in the VLDB (Very Large Database) space with Oracle and IBM. The market share for the product continues to grow, based on total cost of ownership and ease of use.
