But what exactly is cloud migration, and how can it transform your organization’s approach to technology and competitiveness?
Understanding the basics of cloud migration and the various steps involved in making it happen can help you make informed decisions on the best strategy to achieve a smooth transition to the cloud.
This blog will guide you through the intricacies of cloud migration, revealing why it is more than just a technological upgrade—it’s a strategic move that can redefine your business. From small enterprises aiming to boost operational efficiency to large corporations seeking to optimize their technological footprint, understanding the full scope of cloud migration is essential.
What is cloud migration?
The process of transferring data, applications, or other business components from an organization’s in-house infrastructure to a cloud computing environment is known as cloud migration. This process allows businesses to take advantage of the many benefits cloud computing offers, such as increased scalability, reduced costs, and improved disaster recovery capabilities. By adopting the on-demand, self-service model of the cloud, businesses can achieve end-to-end digital transformation and outmaneuver uncertainty.
Why is cloud migration being rapidly adopted?
As technology continues to evolve, many companies are looking for ways to improve their infrastructures and performance. In recent years, cloud computing has become popular among many companies. This is because companies are finding that their legacy systems, such as aging servers or unreliable firewall appliances, are becoming increasingly inefficient and are no longer operating at their optimal capacity. However, it is essential to note that migrating to the cloud is not a simple process and requires careful analysis, planning, and execution to ensure that the cloud solution is compatible with the business’s specific needs.
When planning a migration to the cloud, it is important to consider not only the process of getting there but also what will be done once the migration is complete. For example, companies need to think about how their applications will be rebuilt so that they can perform optimally in the cloud environment. This process is known as application modernization.
What are the various forms of cloud migration?
When moving resources, such as data and applications, from one place to another, the type of resource and the destination location are crucial considerations in the process. These are known as the “workload” and the “migration destination,” respectively, and play a significant role in determining the success of the migration.
This section will explore various migration scenarios and give a general overview of the procedures, recommended practices, and business-related factors involved in them.
Datacenter migration
Datacenter migration involves relocating data from in-house servers and mainframes, typically located in a company’s office, to servers run by a cloud provider. These cloud-based servers are usually found in large, secure, and professionally maintained facilities. The most common method of moving data center resources to the cloud is through high-capacity networks, but if a strong network is not available, resources can be transferred by dragging them onto high-capacity disks or “data boxes” and physically shipping them to the cloud provider for uploading to their servers.
Hybrid cloud migration
Another common migration scenario is hybrid cloud migration, where organizations opt to keep some of their resources on their on-premises servers and move only a required portion of them to the cloud, creating a “hybrid cloud” environment. This approach allows organizations to make the most of their existing on-premises data center equipment while also meeting industry and government compliance requirements. Additionally, hybrid clouds can also be used for cloud-to-cloud backup, which serves as a disaster recovery solution in case the on-premises data center becomes unavailable.
Cloud-to-cloud migration
Cloud-to-cloud migration is a process in which an organization moves its resources, such as data and applications, from one public cloud to another. This type of migration is becoming increasingly popular as organizations adopt multiple cloud environments, often as a result of mergers and acquisitions. By moving resources between different public clouds, organizations can take advantage of various cloud platforms’ products, services, and pricing and optimize their IT infrastructure for cost and performance. Additionally, a central management tool can be used to manage and monitor resources across multiple clouds from a single location, simplifying the management process. This type of migration is also helpful for organizations that want to implement a disaster recovery solution by having a backup of their data and applications in different clouds.
Application, database, and mainframe migration
Migrating applications, databases, and mainframes is a common practice in the technology industry. Different types of workloads can be migrated, such as Linux, SAP, SQL Server, and Windows Server. Mainframe migration is also quite common, with IBM and Unisys being the most commonly used systems. Moving these workloads to the cloud can offer a variety of benefits, such as lower costs, improved performance and reliability, access to cloud-based developer tools and APIs, more robust security, and the ability to quickly scale up or down without the need for additional equipment. While it is possible to move these workloads without making any changes to them (a process known as “lift and shift” migration), there are advantages to updating or “refactoring” them to optimize their performance and reliability in the cloud environment.
What is the process for cloud migration?
Moving a company’s operations to the cloud is a significant undertaking that requires careful consideration and planning. The process of migrating to the cloud can have a profound impact on a business and its operations, making it essential to have a clear understanding of the steps involved. A comprehensive end-to-end view of the migration journey is necessary to ensure that the necessary capabilities and activities are in place to execute the migration successfully.
The process of cloud migration can be broken down into three main steps: Defining your strategy and building your business case, discovery and assessment, and Cloud migration.
Defining your strategy and building your business case
The initial step in the process of cloud migration is to establish a clear strategy and build a comprehensive business case. This step involves identifying the specific business objectives that the company hopes to achieve by moving to the cloud. It is important to remember that migrating to the cloud is not just a technical exercise, but the desired business outcomes should drive it. Once the objectives are identified, the company can start developing a cloud migration strategy and the business case for the move.
A vital aspect of this strategy is determining which applications will be migrated to the cloud and which type of cloud environment they will be moved to. Also, it is important to have a clear understanding of the infrastructure that will be required to support the migration and how it will look like once the migration is completed. This will help determine the specific steps required to prepare for the migration.
Discovery and assessment
The second step in the process of cloud migration is discovery and assessment. This step is critical in understanding the current state of the business’s IT infrastructure, applications, and data. This is done by conducting a thorough scan and assessment of the existing landscape to identify the current architecture and determine the best applications and data to migrate to the cloud. This includes identifying the different applications that the business currently uses, mapping out the dependencies between them, and assessing the risks associated with migrating them to the cloud based on their current usage. Additionally, it may also include optional pre-migration predictive analysis.
The goal of this step is to enable migration planners to make informed decisions about which applications and data to migrate to the cloud and how to do it in the most efficient and effective way possible. By understanding the current state of the business’s IT infrastructure, applications, and data, migration planners can minimize the risk of migration and ensure that the service level agreements are maintained after the migration is complete. The outcome of this step is the Cloud Migration Assessment, which provides a clear and actionable plan for the migration.
Cloud migration
The final step in the process of cloud migration is the actual migration of the business’s IT infrastructure, applications, and data to the cloud. This step is where the majority of the work takes place and typically involves modernizing existing applications for the cloud, developing new cloud-native applications, and transforming the architecture and infrastructure of the business’s IT systems. This step aims to establish a new technology operating system and work culture that allows the company to advance more rapidly, productively, and efficiently.
Automated management and migration tools are essential for executing a smooth migration. These tools not only speed up the migration process but also ensure that it is done with high quality, consistency, and repeatability. When used in combination with specialized skills and solution accelerators, they can form a “cloud migration factory” that can further accelerate the migration process.
It is also essential to have a robust cloud journey management plan in place to keep the migration effort on track. This plan will help ensure that the migration is completed on time and within budget and that the business’s IT systems are fully operational and meeting the required service level agreements after the migration is complete.
Cloud Migration: The Benefits & Challenges
For organizations that embark on the journey of migrating their operations to the cloud, the transition can result in a significant impact on the business.
The cloud computing model provides a range of benefits, some of which are outlined below:
-
