Application Platforms After the walkthrough on how to build clusters, we have seen how many moving parts even a simple application cluster may have: load balancers with a cluster manager, application servers, database servers with replication and a database cluster manager, an object store, just to name a few.
Devops Gen 2 & Infrastructure as Code The emergence of reliable infrastructures — virtual data centers controllable via API — enable new automation strategies in software operations. The usage of persistent disks to store important data on remotely attached block devices makes virtual machines disposable. These ephemeral VMs do not need intense protection as their… Read more »
Virtualization & Clustered VMs Physical clusters provide options to make applications highly available. With the rise of virtualization technologies such as VMware, XEN and KVM it became easy to slice a physical host into smaller virtual chunks known as virtual machines (VMs). This leads to multiple advantages.
