How do you measure the experience and knowledge of an IT professional? One way is through certifications. Earning any certification is a notable achievement, though not all certifications carry the same perceived worth.

IT is a very fast changing industry – what is hot today may be a tiny niche market in only a few years and lesser known things may turn out to be huge trends. That having been said, there are many certifications that will be around for a long time. However, this does not imply that recertification and/or continuing education credits are not required to maintain certification. Predicting the future is always challenging, including in IT, but these certifications are good bets.

If you work in IT, chances are you have your very own IT horror story. Who are we kidding? Chances are you have several IT horror stories.

It was tough, but we compared the stories and narrowed it down to our three favorites who we present here for your (scary) reading enjoyment.

ITIL® 4 reflects new ways of working that have accompanied the digital revolution. Service Management, and ITIL in particular, is still an important toolset but you are now integrating its adoption and use with a vast array of new ways of working (DevOps, Agile, SIAM, Site Reliability Engineering). Since ITIL v3 was released in 2006, a large number of new and updated technologies (Cloud, Serverless Computing, Software-Defined Networking, AI, etc.) have emerged that now need managing. ITIL 4 reflects these changes. Here are some frequently asked questions about ITIL 4, as well as answers that explain what it entails, why we need it and how it differs from ITIL v3.

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.

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.

Multi-factor authentication is a method of logon verification where at least two different factors of proof are required. There are generally three recognized types of authentication factors:

Consider how many financial transactions are performed on the Internet everyday. Protecting all this data is of upmost importance. Cryptography can be defined as the process of concealing the contents of a message from all except those who know the key. Cryptography can be used for many purposes, but there are two types of cryptographic algorithms you need to understand, symmetric and asymmetric. Symmetric uses a single key, whereas asymmetric uses two keys. What else is required to have a good understanding of cryptography? It’s important to start with an understanding of how cryptography relates to the basic foundations of security: authentication, integrity, confidentiality, and non-repudiation.

Routers and switches make up the bulk of network infrastructure and are vulnerable to attack. We hear about mass Denial of Service (DOS) attacks or Distributed Denial of Service (DDOS), but the network itself is as big a risk because if it is taken out, there is no path for the data to flow.

DevOps, which is short for Collaboration between Development and Operations, arose as a movement within IT best practices when IT managers began to realize that something needed to be done to close the communications and collaboration gap between development groups and support operations staff. After some time and examination, it became clear that there was no inherent conflict between the DevOps movement and ITIL—the two, in fact, are quite complementary.
