Cloud Migration Strategy

Cloud Migration strategy happens to be the new buzzword in town. As the name suggests, cloud migration strategy refers to the transition from the conventional approach of association such as services, databases, IT resources, and web and mobile applications to a cloud-based environment. This means that any organization's digital assets can now be stored on the cloud and do not need elaborate on-premises infrastructure.

There are various cloud migration strategies but usually constitute 4-5 stages namely

Preparation

Planning

Migration

Operation

Optimization

The entire process involves careful and meticulous planning throughout the process. Some popular cloud service providers such as AWS, Google Cloud, and Microsoft Azure further simplify this transition process by providing professional and reliable services and support. Before we read into the process, here are a few benefits.

Main Benefits of Cloud Migration

As more and more businesses are switching to the cloud, it is hard to ignore the ways that enterprises are benefiting from this transition. Given below are a few ways advantages Cloud migration delivers:

Scalability

Scalability is a real challenge with conventional assets as it is difficult to increase infrastructure and resources to match the growth of the company. The cost associated with expanding non-cloud infrastructure for storing assets can run high when the company expands.

Cost

Services provided by cloud managers come at a fraction of the cost of maintaining a team to host assets, resources, and data individually as a company. Expenditure on in-house IT operations is manifold compared to when sourced from cloud-supported services and platforms.

Performance

Businesses swear by cloud migration for its ability to enhance user experience and better IT performance. Cloud-led websites and applications are more flexible and accommodating for additional users or throughput, and they can operate in close proximity to end users to minimize network latency.

Disaster Recovery

In the event of software crashes in traditional IT systems, data losses can result in huge losses for the company. In cloud environments, this risk is mitigated and in the event of a crash, the data is backed up on the cloud and is secure.

Digital experience

On a cloud, all data and resources are accessible at any given time and from anywhere. This reinvents the digital experience for users who do not need IT support to access resources or data.

Process of Cloud Migration

As mentioned above, cloud migration entails many stages such as:

The preparation phase includes establishing the goal of the transition to the cloud and the objectives that should be achieved.

The planning phase includes a detailed workflow and planning transfer of assets and their requirements. It also includes choosing the cloud service provider for the migration.

The migration phase involves the actual migration of data while keeping in check with security regulations and policies.

The operation phase includes optimizing operations after it has been migrated to the cloud. It also includes evaluating the cloud's data security and making sure it is in compliance with GDPR and HIPAA.

Types of Cloud Migration Strategies

Originally referred to as 5Rs by Gartner and later expanded to 7Rs, there are seven popular cloud migration strategies to keep in mind. They are

Rehosting is the most basic cloud migration strategy which migrates an application without implementing changes that implement cloud features.

Replatforming strategy revolves around transferring an application to the cloud and implementing some cloud capabilities but not all.

The refactoring strategy revolves around altering the architecture of existing databases and operating systems by porting them.

Repurchasing migration strategy involves swapping internally administered systems for third-party managed services provided by a cloud provider. This strategy allows companies to retire their existing systems while switching to consumption-based, SaaS subscription models.

The retiring strategy refers to discontinuing applications that are no longer required in the source environment and are often incompatible with a cloud environment.

The retaining strategy focuses on maintaining applications in their original environment. This can include applications that need significant refactoring, which can be deferred to a future time, or legacy applications that remain in place due to a lack of business justification for migration.

The relocation strategy is to transfer infrastructure to the cloud without the need for new hardware, application rewrites, or adjustments to existing technologies. VMware Cloud is one such cloud service provider that enables this migration approach.

Conclusion

It is inevitable for businesses to migrate to the cloud, the sooner they do so the better. With the future led by cloud technologies along with AI, ML, and NLP, shifting to a cloud-based environment is the best option. Enterprises looking to undergo this transition should start by looking for an expert Software Development Company. A reliable tech partner can help devise the best SAAS model or reframe existing systems seamlessly while helping enterprises transition to the cloud and provide cloud management services.
