Let's start with defining the job of a cloud architect. You are responsible for planning, designing, migrating, and implementing cloud-based infrastructures, but the effectiveness of these specialists is not guaranteed.

The cloud has been around for over a decade, but great cloud engineers are in short supply. What sets a great cloud engineer apart from simply a good one? Experience plays a big part, and the general expectation seems to be that you will become great by putting in your time. However, the truth is that to be a great cloud engineer you do not just slowly grow into your role. You actively aim for ways to improve both your skills and your approach to using technology. Here are three examples of what great cloud engineers do to be highly successful.

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.

This white paper will explore what questions and factors you should keep in mind as you seek to implement SaaS. Considerations include deciding how your application will be accessed, implementing disaster recovery, scheduling platform maintenance and upgrades, handling service outages and creating a security plan. This knowledge can be useful whether you are provider of SaaS applications or are planning to be a consumer using software for activities like accounting or project management.

The bad guys just keep getting better! No matter how much patching and tweaking we do, the bad guys' constantly changing tactics and techniques continue harming our networks, stealing and damaging data, and just generally screw things up. What motivates someone to do such terrible things in the first place? How have these hackers changed and improved? What kinds of attacks are popular now and why? In this hour-long webinar, security expert, former hacker and Global Knowledge instructor Phillip D. Shade will provide insight into understanding the latest hacking techniques, what the current threat landscape looks like, and suggested countermeasures to mitigate threats. He will include specific examples of the current threat landscape, including data mining, social engineering cyber threat terminology, man-in-the- middle attacks and Denial of Service (DoS) attacks.

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.
