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.

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.

Businesses today are more dependent on technology than ever. And, more than ever, they're looking to IT for ways to improve employee productivity, customer service and innovation. The challenge is that in order to achieve results with technology, IT and the business have to work collaboratively. IT needs to be able to develop the right relationships and communicate with different stakeholders from a business perspective - not a technical one. As a result, the transformation of the IT department has become a top-level priority for many leading organizations. At the same time, business leaders need to strengthen their business technology IQ and play a more significant role in the governance of IT.
Cisco Internetwork Operating System (IOS) has been around since a little after the inception of Cisco Systems as a company. In 1984, Len and Sandy Bosack from Stanford University founded Cisco Systems with a small commercial gateway server. The first Cisco router that I touched was an Advanced Gateway Server (AGS), which was the first marketed product of the company. After this came the Mid-Range Gateway Server (MGS), the Compact Gateway Server (CGS) and later the Integrated Gateway Server (IGS) and AGS+. The first version of IOS that I touched was 8.2(7). The operating system was based on a Unix-based system and was designed as a monolithic operating system, meaning that processes are stacked and interrelated.
A strong event management process that is able to detect changes of state throughout an organization’s IT environment is a key aspect of a complete suite of service management processes. Event management ultimately helps an organization maintain control through an understanding of the state of things, and how the state of those things changes in an IT environment.
Event management, although theoretically different, is fundamentally what most IT organizations refer to as “monitoring.” Monitoring an organization’s environment to determine whether important assets are in the state they should be, and knowing when that state changes, is a very important activity that many organizations spend significant portions of their budget doing.

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.
Young adults unable to find work, employers unable to fill jobs, a recent GAO study that reported substantial declines in telecommunication expertise — there has been a lot of news about the pervasiveness of skills gaps, their causes, the actual impacts and what to do about them. It’s rather confusing, because the term “skills gaps” has been hijacked to politicize an extremely wide range of issues.
