The process of moving a company’s digital assets, services, databases, IT resources, and applications into the cloud is referred to as cloud migration. This could be a partial or complete migration, and could also involve moving from one cloud to another. Companies are turning to the cloud as a solution to outdated and inefficient legacy infrastructure and to improve performance and efficiency.
However, migrating to the cloud is not just a matter of getting there. It requires careful planning and execution to ensure compatibility with the company’s business requirements. One important aspect of cloud migration is application modernization. This refers to rebuilding applications to perform optimally in the cloud environment.
The process of cloud migration is complex and businesses of all sizes may require assistance. This is where service firms come in, offering lift-and-shift cloud migration capabilities or classic modernization services such as automated language translation and re-platforming.
Undertaking a cloud migration journey requires careful planning and execution. By taking a comprehensive approach, you can ensure that all necessary capabilities and activities are in place to successfully move to the cloud. There are three main steps involved in cloud migration:
Defining your strategy and building your business case: The first step is to determine the business value that can be gained from moving to the cloud. This involves setting specific business objectives and developing a cloud migration strategy that aligns with these objectives. It also involves determining which applications should be moved to the cloud and what the infrastructure should look like.
Discovery and assessment: To minimize risk, it is crucial to understand the current state of your infrastructure, applications, and data. Through discovery and assessment, you can identify which applications and data are suitable for migration, and assess the risks involved.
Cloud migration: This step involves the actual migration process, including modernizing existing applications, developing new cloud-native applications, and transforming the architecture and infrastructure. The goal is to create a new technology operating model that enables innovation and efficiency.
The use of automated management and migration tools can greatly simplify the migration process and help ensure high quality, consistency, and repeatability. A robust cloud journey management plan is also critical to keep the effort on track. With specialized skills and solution accelerators, a cloud migration factory can be established to accelerate the journey even further.
Now that you are familiar with the various options available, it’s time to discover the benefits of cloud migration.
You no longer need to invest in expensive server equipment, deal with maintenance costs, or pay high electricity bills. Additionally, operational costs are reduced as your DevOps specialists and system administrators won't have to spend time on backups and hardware maintenance. With cloud vendors offering pay-as-you-go pricing, you only pay for the computing power you use. Emirates, for example, moved to the cloud in 2020 to reduce hardware maintenance costs and accommodate traffic changes due to Covid-19. The company is expected to save $1 million annually by retiring its outdated hardware.
By having your workloads in the cloud, you can quickly adapt to peak demands and reduce capacity as needed. This is done automatically without much effort, saving you time and resources. With on-premises hosting, you would need to purchase and install additional equipment to increase capacity, even when you don't need it after the load spike passes. Yedpay, a payment platform, migrated to the cloud after experiencing a data center issue and was able to reduce costs by 40% by eliminating the need for extensive IT investments and physical infrastructure maintenance.
Reliable cloud providers continually upgrade their services to meet the latest industry standards and regulations to reduce the risk of cyberattacks. Gartner predicts that up to 99% of cloud security failures through 2025 will be due to customer error.
Although not all cloud deployments go smoothly, migration to the cloud can reduce downtime and lower the risk of data loss in the future. Most cloud vendors have service-level agreements that guarantee 99% uptime, and they are responsible for backups and disaster recovery, freeing up time for your team. Under Armour, and Connected Fitness faced a reliability challenge with their two data centers, but migrating to the cloud successfully resolved the issue.
From a business growth perspective, the cloud offers unlimited opportunities for organizations, and it also speeds up digital innovation. With the tech flexibility offered by cloud providers, your development teams can optimize and accelerate workflows. Capital One, a large U.S. bank, reduced development environment build time from months to minutes after migrating to the cloud.
Cloud computing allows you and your team to access applications from anywhere in the world at any time, providing flexibility for remote work.
The impact of cloud migration on companies can be tremendous. This transition brings about a decrease in ownership costs, quicker delivery times, and new opportunities for innovation. With the cloud, businesses gain agility and flexibility, two crucial elements for responding to changing consumer and market demands.
In recent times, companies have been migrating their services and data to the cloud to adapt to the rise in remote working and online demand. Those who have already started this journey are fast-tracking their cloud transformation and leading the way for the future. Those still considering the move, may be asking themselves, “Why did we delay?”
