Boosting CloudStack Reliability
Reliability and Usability are two key features that software systems must adhere to. Be it users, developers or businesses, they are all first and foremost interested in understanding whether the system is usable for their requirements and whether it is dependable enough to not fail.
One of the crucial factors that influences both these capabilities is configuration. It is obviously a necessary part of setting up a system before using it, but the right configurations can also help you get the most out of your infrastructure. In addition to this, the ability to maintain configurations determines the stability of your setup.
In the context of CloudStack and VMs, there are various scenarios like live migrations, addition of new VMs to a cluster or host restarts, where maintaining configurations is a challenge. It becomes a major operational problem when for example, there is a loss of iptables information or when there are missing port profiles or when IP addresses have not propagated to all required VMs.
What if these issues could be addressed. High Availability, Load balancing, clustering are eventually all aimed at making a system remain consistent and “present”. To this end, we have some ways that can help you achieve improved results in these areas with CloudStack.
Accelerite recently presented a paper on how to “Improve reliability of Apache CloudStack over VMware deployments” at ApacheCon North America 2017. The paper explains some of the issues faced during migrations and restarts, and solutions to make your cloud deployments more dependable. It also demonstrates how these can be implemented via configurations and more. Take a look at the paper here. Feel free to reach us at firstname.lastname@example.org if you have any queries.
On a related note, Accelerite has launched its enterprise hybrid cloud platform, Rovius Cloud, that lets you build an on-premises cloud in minutes using commodity hardware. Rovius Cloud upgrades with no downtime and lets you painlessly expand workloads to a public cloud. Learn more about Rovius Cloud here.
