As cloud adoption has risen in the last 5-6 years, many firms have migrated to public and private cloud deployments. The global impacts from COVID-19 on work from home and remote computing demands have exacerbated this initiative.
Both of these have their pros and cons, resulting in the need for resilient, multi-cloud strategies and architectures.
Cloud services are like building blocks, but many cloud providers’ services can be layered on top of each other, adding complexity, which makes back-ups challenging at best.
As the Cloud Services Providers have evolved, many have implemented solutions and offer their own proprietary tools and systems to manage their environment to their user firms. However, a number of these solutions and services are proprietary, and while unique to the CSP, can provide enhanced levels of control and security.
Connecting to CSPs global data centers and mapping failovers and data back-ups to other cross-cloud providers has presented significant challenges to firms that use them.
Firms that migrated to the cloud from on-premises or co-located data centers have often architected a back up to another CSP entity, to reduce vendor and concentration risks from network or infrastructure failures.
In response to the rise in cloud migration and cloud computing strategies, Tellefsen and Company has recently developed a Framework for Developing a Cloud Computing Strategy for Disaster Recovery. This document highlights:
· Cloud Adoption in Financial Services
· Cloud Repatriation
· Why do Companies Migrate Back to On-Premises?
· Cloud Based Disaster Recovery
· Test Pre-Requisites
· Site and Database Recovery
· Proof of Concept Testing
· Set up the DR Environment
· Identify Key Risks
· Develop a BC/DR Test Plan
· Pre-Test, Test Day and Post-Test Activities
· Conduct of the Test
· Identify Potential Open Issues
The following is our strategy document:
