Top Mistakes to Avoid when Migrating to Cloud
Cloud migration is becoming essential for large Businesses but for the same reasons as bigger companies, small businesses are attracted to the cloud: lower costs, flexibility, collaboration and virtualization, allowing companies to accomplish more with less resources.
But in the face of hard choices about where to start, safety concerns and the huge number of providers to select from, the idea of cloud migration often overwhelms us.So breifly we can summarize it as Start simply, and design a plan first and foremost.
But as we move closer to cloud computing, it's critical to understand the shortcomings of on-premise cybersecurity policies in cloud-native environments
.
So lets discuss some of the common Mistakes to be avoided to have a successful cloud migration
Not caring about security:
Our human brains can barely comprehend the magnitude of the data cybercriminals would be able to steal in the near future and how damaging it can be to businesses of all sizes.Startups are still more likely to overlook security until something goes wrong.Implementing security measures later might have an impact on your team's productivity and potentially create downtime, so it's best to get something in place right away.
Lack of Maintenance
Create security boundaries, so policies are simpler and easier to maintain.In customer-facing (production) environments, set least-access policies, starting with the bare minimum and adding access as it’s necessary.Any changes in production environments must be made by using infrastructure-as-code, tested in non-production and peer-reviewed before deploying.Make sure firewalls (security groups) allow only granular access to the services, never with a rule allowing the whole network or all ports.Make sure code is peer-reviewed before going to production — this can be enforced by setting branch permissions in your GIT repository to only allow merging a pull request to the master branch with multiple approvals.
Absence of a CI/CD pipeline:
The automation and frictionless deployment are made possible via a Continuous Integration / Continuous Deployment (CI/CD) pipeline. Many advantages come from having code built, tested, and delivered through a pipeline, such as visibility into what is deployed and a “single source of truth” for building, testing, and delivering your code.additional deliveries and features faster reach your users.Make sure the tool you select supports pipeline-as-code and begin from the beginning.
Using the All-Or-Nothing Approach
Not all corporate apps are good candidates for cloud migration. Shifting all of your existing infrastructure and services to the cloud at once is a common cloud migration mistake made by enterprises. This method is rarely successful.Some programs may have a complex code structure, while others may be running on legacy technology stacks, causing maintainability concerns and rendering them unsuitable for cloud transfer.
Backup and Disaster Recovery
Designing for failure entails putting in place safety nets to ensure that any outage causes as little harm as possible.
Designing the architecture with a failure mindset results in the adoption of a fault-tolerant, cloud-optimized architecture. The recovery mechanisms would be integrated into the design, ensuring little loss and optimal output even if the cloud architecture failed.
Concluding Remarks:
It is necessary to transmit to all levels of the organization the choice for data and apps to the cloud. In addition, adequate contingency planning and training for employees should be in place to allow a smooth transfer.and do not take security Forgranted because you ahve to pay huge in return of this mistake
Adequate planning, strategy and vision are necessary to effectively conduct a cloud migration. A clear understanding of what you want to achieve, the actions to be visualized and implemented simplifies, all contribute to the success of cloud adoption.
