In the Datacenter world, achieving Application Resilience is a very difficult and expensive task. Its cost comprises not only the 2.5x Infrastructure cost that you must include in your IT budget, but also the manual hours of your expensive IT, networking, application, and DBA teams working together for hours to do a DR drill, as well as the backup service running and management costs. Small and medium firms find it difficult to afford DR as a result. With Appranix’s capability and the emergence of multiple cloud-native services, a new innovative form of Application Resilience is now accessible to everyone.
What is Application Resiliency?
In today’s environment, applications are growing increasingly complex and distributed, as are their infrastructure requirements. Application resilience is the result of combining infrastructure and data resilience for a particular set of application components. Technically, in a well-architected environment, the combination of your infrastructure’s high availability and data backup at a point-in-time in two more locations gives you Application Resilience, assuming your application is appropriately designed for it.
What is Cloud Application Resiliency?
In simple terms, cloud applications resilience is about “the ability of the central operations teams to recover entire application environments rapidly, including data, applications, configurations, dependencies and state at a particular point-in-time from any kind of failure, be it, at the cloud level or platform or application level in any region of the cloud.”
The cloud has brought a wealth of capabilities, including infrastructure automation, infrastructure availability across many regions, snapshot technologies, networking, and cross-region data transfer with much faster replication. Because cloud technology has progressed, it no longer makes sense to employ traditional backup software in the cloud to achieve data center like resilience for a variety of reasons, including:
- Slow and risky: You don’t want your data to be transformed into a proprietary format and stored in your backup vendor’s Cloud account, incurring additional storage fees. This not only increases liability for your company as the data now resides somewhere else but it is harder to convert back and forth.
- Operations cost: You don’t want to install backup agents in your environment to secure your data because the cloud already has snapshot capabilities. Agents present continuous maintenance and upgrade issues.
- Increased cloud cost: You don’t want to install and administer one or more backup manager systems as part of your infrastructure, thus you’d pay for what the backup vendor runs in your Cloud environment as well.
- Expensive low resilience: You do not need to run the backup manager on your DR region as it is difficult to protect across more than one region.
Challenge Achieving DIY Cloud Application Resilience
Even now, there are smart teams, either in-house or outsourced, with some Terraform provisioning scripts out there trying to automate the DR infrastructure. Even though this method appears to be plausible, with a DIY for creating application resilience, you will be unable to perform a DR effectively even once, and it will take a long time to get your infrastructure as a code in sync with your continuously changing production infrastructure. Not only the infrastructure is the problem, but your application data from backup systems or storage systems will be much harder to sync with the right version of the infrastructure, and applications that could guarantee a running application in another region of the cloud are much harder.
Smart IT leaders understand what is genuinely desired, as well as the flaws in old legacy approaches.
The solution: You could self-service your application resilience on the cloud, easily!
All of these complexities can be unified and simplified when Application Resilience in the Cloud is delivered as Software as a Service (SaaS), with no agents required, no proprietary data conversion, no backup manager or in the DR site, and no need for you to manually maintain Infrastructure scripts.
