Have you heard the news? The CloudU program has moved to a new social Learning Management System (LMS). The new CloudU site is available now. If you have completed the CloudU Certification program, you should have received an email with instructions on how to log in to the new system. If you have completed the program and have not received an email with login instructions, contact us at email@example.com.
If you registered on this site prior to February 4th, 2014 and are working on completing the program, we encourage you to complete it by March 31, 2014, the last live date of the program on this system.
Programming & the Cloud, Preparing the Developer for Tomorrow
The advent of Cloud Computing has removed infrastructure as a barrier to rapid and massive scaling of applications. Whereas in the past the need for physical hardware created a drag upon the entire scaling process, the ease of use and accessibility of Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) has made it possible for a developer to create an application one day and have it utilized by hundreds of thousands of users the next.
This paradigm shift in terms of scale, geographic spread and velocity has changed the development process markedly - no longer do developers have the luxury of creating an application and scaling that application in a controlled & generally sedate manner. Instead the velocity of today means that they need to think about scale and speed from the outset.
At the same time, modern web applications are architected in an entirely different manner with traffic to and from the application via Application Programming Interfaces (APIs) amounting for a significant proportion of total traffic. This change in the ways data is being created, stored and consumed by an application has also changed the demands on developers.
Disaster Recovery -- Continuity in an Uncertain World
Disasters are an inevitable certainty for any organization -- but while inevitable, disasters are also generally unpredictable. The best strategy then in the face of inevitable but uncertain negative events is to have a holistic plan that sets out the process by which an organization can return to normal operations after a disaster.
This paper will define some core concepts around disaster recovery, contrast it with the related but distinct field of High Availability, and give some key guidelines as to how an organization can plan, react and recover from a disaster.
We've been busy at CloudU making some more videos to help people understand the cloud. The latest video looks at the Cloud Computing Stack, diving into Software-as-a-Service, Platform-as-a-Service and Infrastructure-as-a-Service. Check it out and let us know what you think.
