USE CASE

Main factors on which the Disaster Recovery Plan acts to ensure business continuity

Backup and Disaster Recovery projects are one of the entry solutions that many companies use to validate the cloud as a business continuity strategy. The main risks of downtime for the Planeta Huerto website occur when it requires more resources and they cannot be provided because the maximum limit has been reached. 

In this case, the two ways to increase the limits were specified for both the application layer (backend, middleware and frontend) and the database layer.

Other crashes could occur due to the following factors:

• • Table crash in Database.
  • Deployment with a bug in the application.
  • DDoS attack.

In reality, there are a multitude of threats that can cause a website to crash. The most common ones have already been specified. But the important thing is to have a defined process in operation to recover data and functionality in the event of a system crash caused by a catastrophe, whether natural or intentional.

In our approach, we have the key indicators RTO and RPO 

• • RTO (Recovery Time Objective): the maximum amount of time that business activity can be halted.
  • RPO (Recovery Point Objective): the previous point in time to which we are willing to return to recover business data and functionality.

Configuring and managing alerts

In addition, alerts were set up in case of a fall:

• • Preventive alert that warns us when a certain percentage of criticality is reached.
  • Alert that allows us to know when the service is down before a customer calls us.
  • Health check configuration to know when the service has been restored.

The tools we use for this project are DataSync,  S3 and AWS Storage Gateway. In this way we can develop customized solutions to upload data to the cloud on a scheduled basis and retrieve it automatically if necessary. We also integrate Veeam Backup services in cloud environments for further storage optimization and agile operations.

A Disaster Recovery System has to provide a stable and robust solution that is capable of recovering a critical system in minutes. For this we use the AWS Elastic Disaster Recovery service which offers us a perfect solution to keep your standby system synchronized and ready to take control of your production loads in the event of a problem.
