Automating Disaster Recovery Across Multi-Cloud Environments
Declarative Disaster Recovery for Current IT Infrastructure
In the past, disaster recovery plans were often written down. They explained the steps, but they relied a lot on people doing them. That method doesn’t work in today’s hybrid and multi-cloud settings. It is not possible to rely on manual recovery because systems are too dynamic, distributed, and automated.
The model changes with Disaster Recovery-as-Code (DR-as-Code). Instead of writing down how to recover, businesses use infrastructure templates to define recovery environments. The environment is rebuilt automatically when something goes wrong.
This method makes recovery easy to predict, repeat, and test.
What Does Disaster Recovery-as-Code Mean?
DR-as-Code uses the same ideas as Infrastructure as Code to keep businesses running. Administrators use declarative configuration files to set:
- Resources for computing
- Setting up the network
- Mappings for storage
- Policies for security
- Workflows for restoring backups
Automation platforms recreate systems based on stored configuration instead of having to rebuild them by hand.
The same file that sets up production can also set up recovery.
Why Traditional Disaster Recovery Doesn’t Work
There are a few problems with manual disaster recovery.
- The information in documents gets old.
- Execution by humans makes mistakes.
- How long it takes to recover depends on how many staff members are available.
- Testing is not done very often because it is disruptive.
These problems get worse as systems grow across cloud platforms and remote sites. A recovery plan from two years ago can’t be counted on to bring back a modern infrastructure.
- Automation fixes this by making recovery a normal part of business.
- Terraform is an infrastructure-as-code tool used for disaster recovery.
Terraform makes infrastructure by using declarative configuration. You can write code that describes a full recovery environment and set it up in another region or provider in just a few minutes.
If the main site goes down, a secondary environment can be automatically set up again with the same settings.
Ansible
Ansible takes care of the state of the application and the settings. Once the infrastructure is in place, Ansible sets up services, mounts storage, restores data, and checks to see if the application is ready.
Terraform builds the environment, and Ansible gets it ready to work.
Making a framework for recovery across multiple clouds
A scalable DR-as-Code strategy is based on layered architecture.
- The infrastructure layer makes networks, subnets, and compute instances again.
- The platform layer installs the operating systems and other software that they need.
- The data layer brings back databases and storage.
- The application layer checks to see if a service is available.
There is version control and automation for each layer.
When recovery starts, the whole stack deploys in order without any help from a person.
Keeping Data Safe in a Declarative DR Model
Data is not safe just because of automation. Recovery relies on dependable backup architecture.
Backups need to be stored outside of the failed environment and be available in other regions. Replication of storage, backups that can’t be changed, and recovery points that are versioned are all very important.
The recovery code points to backup locations instead of local disks. This makes sure that new infrastructure can get data even if the original site is down.
Synology’s Part in Automated Recovery Architectures
Synology storage platforms work well with DR-as-Code because they give you access to backup repositories that are always the same across all sites. Snapshot replication and centralized backup management let recovery automation mount restored storage without having to set it up by hand.
From one place, backup services keep virtual machines, servers, and application data safe. Recovery workflows can automatically get backup images and add them to new infrastructure. This makes recovery faster and easier to set up.
This lets infrastructure templates rebuild both the data environments and the compute resources at the same time.
Benefits of Declarative Disaster Recovery
Companies that use DR-as-Code see real benefits.
- Instead of being a process, recovery becomes something that can be predicted.
- Testing is no longer a bother; it’s a normal part of life.
- Failing over to multiple clouds becomes possible instead of just a theory.
- In times of crisis, mistakes made by people are less likely to happen.
Most importantly, recovery time goals become possible because the process is automated instead of being made up as you go along.
Epis Technology is about
Epis Technology makes automated recovery frameworks that work with both infrastructure automation and enterprise backup systems. They put together storage platforms, replication strategies, and configuration management tools into a single recovery architecture.
Their method makes sure that companies can rebuild environments in other places using verified backups and scripted deployment workflows. Epis Technology helps businesses turn disaster recovery from a manual process into a reliable operational capability by aligning backup design with automation tools.
