High availability configuration for VMs in SCE+ is directly proportional to the SLA a customer has selected for his virtual machine while provisioning.
A couple of months ago, I heard about IBM SmartCloud Provisioning under the code name HSLT: High Scale, Low Touch provisioning engine. This product is all about bringing a true “as a service” approach into the infrastructure world. That’s what the brochure says anyway.
Today, we are used to speaking about desktop or test clouds, or maybe moving our email or CRM to cloud-based solutions. What do all these workloads have in common? They have some of the main characteristics to be a good candidate for cloud computing, but beyond that, they all are related to enterprise workloads with low or non-predictable demand for computing resources, do not generate a significant amount of data during application run, and are loosely coupled to the infrastructure.
In the “Rapid deployments with IBM SmartCloud Provisioning” blog entry, we have shown that virtual machines or appliances can be started and configured in a matter of seconds. It has never been so easy to create a virtual machine (VM), install software, and configure middleware. However, with great power comes great responsibility…it is now possible to create a VM, but what is its lifecycle? Will it be destroyed after being used, is the starting image deprecated, or is there a better starting image given the needed configuration and software install requirements?
In today's dynamic environment, new thinking is required when it comes to security, especially because the infrastructure is more abstract and less defined, everything needs a web interface, agents and heavy clients are not acceptable, and traditional defences no longer apply.
