Cloud migration is the process of migrating business applications from a provider’s own on-premises infrastructure or cloud to another provider’s cloud platform. The company receives a virtual pool of the resources it needs – computing, networking, storage – and reduces administration costs, and improves the quality of customer service.

Thanks to virtualization:

  • Increase the flexibility of the IT infrastructure. It is easier and faster to scale, customize, and reconfigure.
  • Business risks are reduced. The transition to higher-class equipment with well-established monitoring systems and protection of infrastructure from third-party influences increase the stability of the business.
  • Grows productivity. No need to squeeze 110% of the power out of obsolete equipment or use it at 70%. Cloud resources allow you to consume as much power as the company needs right now.
  • Data security is guaranteed. Sophisticated multi-level information protection systems of the cloud provider provide more reliable protection of confidential information.
  • Compliance with standards is ensured. The infrastructure of the cloud provider regularly undergoes the necessary certifications and attestations. Due to this, customers receive solutions that meet the requirements of national and international legislation.
  • Cost optimization. The company gets rid of the need to invest in equipment, maintain a large IT park, and have a staff of specialists servicing equipment.

Companies’ IT infrastructure is typically a hybrid of public, private cloud, and on-premises hardware. According to surveys, 73% of CEOs of large companies are already working with this combination of resources, and another 17% intend to do so in the coming months.

Why you need to migrate to the cloud infrastructure

Moving to the cloud will help in many ways based on the individual company goals. Some people use the IaaS model to move IT infrastructure to the cloud to increase data storage capacity or speed up computer operations, while others use the cloud as a backup platform for testing, development, or hosting non-critical services.

To put it another way, hiring a cloud server boosts overall corporate productivity. The firm gains access to computer resources, storage systems, and communication routes without incurring capital costs or the need to operate its own server room.

Moving to the cloud is the first stage toward digitalization, which is critical for every company that wants to stand out in the market and start new IT initiatives.

Migrating to the cloud is a smart choice when a company’s business applications are consuming more resources than on-premises hardware can handle, or when the in-house infrastructure is outdated to meet current business needs.

An old low-powered server or other equipment seriously harms the company’s business processes, slowing down the work of all departments. In addition, there are security risks as vendors stop supporting legacy hardware by discontinuing security updates.

Using aging systems is inefficient in the long run. The company will still face performance issues, growth constraints, and security risks. Seeming savings on upgrades are actually detrimental to business. Moreover, PCF to Kubernetes migration is already being offered today as a more technological and modern solution.

Cloud solutions outperform on-premises infrastructure by a long list of criteria. The cloud is easier to maintain, operating costs are lower, and changes to applications can be made much faster.

Types of cloud migration

There are two forms of migration: internal and external.

  • from physical to virtual infrastructure
  • from one cloud platform to the next (from another provider)

This method necessitates planning, but it is typically worthwhile because it results in cost savings and more flexibility.

There are numerous ways to migrate apps to the cloud, ranging from transferring existing applications “as is” to creating a new app to replace the old one.

Simple motion (Lift-and-shift). The applications of the company remain unchanged; they are simply stored in the cloud. Copying application executables, building and setting virtual machine (VM) pictures, creating security groups, setting Elastic IPs and DNS, and transferring to a new cloud database are all examples of lift-and-shift operations.

Refactoring. The strategy entails adapting the program to function in a cloud system. Because it includes reusing software applications and making code modifications, this procedure may take some time. However, the refactored program is able to fully utilize the cloud architecture in the end. This method is useful when transferring older apps. In terms of the long business results, we may argue that refactoring is by far the most effective way.

Re-platforming. A hybrid technique in which the system architecture is somewhat refined. Implementing a controlled database or leveraging dynamic scalability features, for example. Although this process takes more time than the first, the firm becomes more productive and cloud-ready. There are some other advantages. Implementing autoscaling for internal workloads, for example, might relieve DevOps of the effort of manually maintaining instances.

Conclusion

Cloud migration might alter your company’s functional responsibilities and processes. While the workflows themselves will not change, the working environment will. Selecting a provider, establishing security, and ensuring that applications and services integrate with the cloud environment are all major challenges for the firm. The remaining procedures have been well tested and do not create any issues.
