Cloud Migration: Benefits, Challenges, and Best Approaches
Cloud migration is a procedure that refers to shifting digital company operations to the cloud from old traditional business operations. This entails transferring data, apps, or other business pieces to a cloud computing environment. Moving data and apps from a local, on-premises data center to the cloud, for example.
Migration from on-premises to cloud:
Every firm, from small to large, has a slightly different procedure for cloud migrations. Some of the common aspects that are considered prior to cloud migration are as follows:
- Performance and requirement evaluation
- Cloud service provider selection
- Operational cost estimation
The fundamental steps are as follows:
- Setting migration objectives
- Developing a security plan
- Existing database replication
- Business intelligence should be moved.
What are the primary advantages of moving to the cloud?
Cloud computing can quickly scale up to support larger workloads and more users than on-premise infrastructure, which needs businesses to buy and install extra physical servers, networking equipment, or software licenses.
Companies that migrate to the cloud typically pay far less for IT operations since cloud providers handle maintenance and upgrades. Instead of focusing on keeping things functioning, businesses can devote more resources to their most pressing business demands, such as developing new goods or upgrading existing ones.
Moving to the cloud can help certain firms enhance performance and the overall user experience for their consumers. If their application or website is hosted in cloud data centres rather than on-premise servers, data will not have to travel as far to reach customers, resulting in lower latency.
Users, whether employees or customers, can access cloud services and data from any location. This makes it easier for a company to expand into new markets, offer its services to a global audience, and allow its personnel to work flexibly.
What are the key hurdles of cloud migration?
1) Migrating large databases
Large databases must often be migrated to a different platform entirely in order to function in the cloud. Moving a database is challenging, especially when huge volumes of data are involved. For large databases that would take too long to transfer over the Internet, some cloud providers offer physical data transfer options, such as loading data onto a piece of hardware equipment and then sending the appliance to the cloud provider. Data can also be sent via the Internet. Data migration, regardless of method, frequently takes a long time.
2) Data integrity
Once data has been transported, the next step is to ensure that it is intact and safe and that it is not leaked during the process.
3) Continued operation
During the migration, a company must ensure that its current systems remain active and accessible. They will need some overlap between on-premise and cloud to provide continued service; for example, before shutting down an existing database, all data must be duplicated in the cloud. Businesses must often move in small steps rather than all at once.
What cloud migration approach should businesses use?
Gartner, a well-known information technology research firm, describes five possibilities for organizations considering cloud migration. These cloud migration tactics are known colloquially as the “5 R’s”:
- Rehosting can be defined as “the same thing, but on cloud servers.” Companies that choose this option will choose an IaaS (Infrastructure-as-a-Service) provider and rebuild their application architecture on that infrastructure.
- Refactoring entails reusing existing code and frameworks while running applications on a PaaS (Platform-as-a-Service) provider’s platform rather than IaaS, as in rehosting.
- Revise — This method entails partially rewriting or expanding the code base before releasing it via rehosting or refactoring
- Rebuild — “Rebuild” means rebuilding and re-architecting the application from the ground up on the platform of a PaaS provider. This can be time-consuming, but it allows developers to take advantage of new PaaS vendor features.
- Replace — Businesses can also choose to replace their existing apps with pre-built SaaS (software-as-a-service) applications from third-party suppliers.
What role do Reveation Labs play in cloud migrations?
Reveation Labs provides a single control plane for the performance and security technologies required for successful cloud migration, such as DNS, load balancing, and the Cloudflare WAF. These solutions are completely connected and can be administered from a single dashboard (see a case study on cloud migration). Reveation Labs interacts seamlessly with any cloud deployment, whether public, private, hybrid, or multi-cloud.
Finally, cloud migration provides several advantages and chances for enterprises. It allows for scalability, flexibility, cost-effectiveness, and enhanced security. Organizations can streamline their operations, improve collaboration, and gain access to innovative technology by shifting to the cloud. Successful cloud migration, on the other hand, necessitates careful planning, consideration of business objectives, and proper execution. During the migration process, it is critical to analyze the preparedness of the existing infrastructure, select the appropriate cloud provider, and ensure data integrity and security.
