We hear the term cloud migration or moving to the cloud very often in our daily lives. Sharepoint, Zoom, Office 365, Google Drive, or Gmail - you have most likely used one or more of these. As a result, you are also likely to have interacted with ‘cloud’. Cloud is essentially a virtual data center on the Internet i.e. an Internet server where you can store or access data without having to keep them in your computer’s hard drive. In this blog, we will highlight some of the major benefits of cloud migration. These help us in performing our jobs easily.

What is Cloud Migration?

The process of migrating business applications and data from on-premise architecture to the cloud, which is a virtual supply of scalable computational, network, and storage resources, is known as cloud migration. There are four types of cloud migration. They are lift and shift, shift to Software-as-a-Service (SaaS), application refactoring, and re-platforming namely. Cloud migration is essential for expanding the business infrastructure. When you are migrating to the cloud, you need to be clear on your end goals. With that in mind, let’s dive into what makes cloud migration so unique and essential in today’s world.

Benefits of Cloud Migration

Cloud migration services enable you to manage your IT infrastructure totally from a distance while eliminating the security risk, hassle, and cost of maintaining on-premise infrastructure.  It is something that helps us to process and, or move our digital assets. For many companies, cloud migration is a huge blessing. That’s because, with cloud migration, their data can expand and grow within their existing infrastructure without affecting their business performance or customer experience.

Let us delve a little deeper into the numerous wonders cloud migration can accomplish for us. Now that we have a better understanding of what it is and how it can help us, we are ready to learn about its benefits in detail. Some of the most valuable benefits of cloud migration are:

• Easy Integration and Access

• Increased Staff Flexibility and Collaboration

• Reduced Infrastructure Complexity

• Enhanced Security

• Easy Flexibility and Scalability

• Simplified, Built-in Monitoring

• Improved Cost Management

Easy Integration and Access

Based on corporate demands and consumer desires, cloud migration services and applications are constantly developed, updated, and expanded. Normally, a company that uses a data center would have to do an infrastructure refresh regularly to maintain its data center software and hardware current and functional. This is a long-consuming, costly, and monotonous activity that wastes valuable time and resources. Instead, at the end of a hardware refresh cycle, enterprises can now transfer apps and other data to the cloud. In the cloud, the cloud provider handles hardware and software updates. This helps to save two essential assets. Namely, your money and your time. It also helps to ensure that the applications are always backed up by the most recent infrastructure.

Increased Staff Flexibility and Collaboration

With cloud migration, companies can now have increased staff flexibility and enhance collaboration in all respects. Your team won't need to be in a certain location to deploy, upgrade, or fix issues with any of the machines they're using thanks to cloud services. In comparison to the requirement of being on-site, this makes it a more flexible option. Besides that, since everyone is on the same page with the cloud's uniformity in resource allocation and deployment processes, collaboration can be much easier, eliminating the need for shadow IT.

Reduced Infrastructure Complexity

Cloud migration helps to lessen the infrastructure complexity by a lot. In reality, cloud systems tend to overlook the difficulty of the infrastructure that forms the basis of the layout used to deploy automated technologies. These cloud systems force them all to work together to provide the required services. Alternatively, you can enter some information about what is needed and begin the essential assistance. Because those particular intricacies are no longer a part of your process, you can save a lot of time. Cloud infrastructure may be launched and put to work in minutes, rather than waiting weeks or months for physical equipment to arrive. Furthermore, cloud-based resources such as managed cloud databases simplify the deployment of new services, allowing smaller development teams to accomplish more.

Enhanced Security

The cloud provides significantly higher security than traditional data centers since it stores your business information and data centrally. Many built-in security capabilities, including security analytics, frequent upgrades, and cross-enterprise visibility, are available from the majority of notable cloud providers. Just about all cloud providers handle some of the more difficult security issues. These may be issues like preventing unauthorised traffic from accessing the machines where your company's data and applications are stored. And they also ensure that their systems receive automatic security updates to keep them safe from the latest known security threats. Many public clouds provide built-in security measures as well as specialised cloud security tools to assist protect an organization's resources. In many circumstances, the cloud provider performs security patching automatically.

Easy Flexibility and Scalability

Companies just need to pay for the cloud resources they utilise, eliminating the need to pay for and maintain IT assets that are only used occasionally. Organizations can change their resources on-demand if demand increases or if they require more powerful computing resources. Many businesses use a hybrid cloud strategy, in which some workloads are moved to the cloud while others remain on-premises. This allows them to get the most out of their existing IT expenditures. (Hybrid clouds may also provide benefits in terms of industry compliance.) Most cloud platforms have a global presence, allowing businesses to improve performance by bringing workloads closer to their users or customers.

Simplified, Built-in Monitoring

Already many cloud providers offer monitoring, which makes it possible for you to be informed when an app or machine is having difficulties or is down. Organizations can manage and monitor their on-premises data centres and cloud resources from a single screen if the cloud provider provides a central management platform. Of course, compared to keeping a check on the state of your services on your own, this process of cloud migration can save you a lot of time. A way of reviewing, watching, and managing the operational process in a cloud-based IT infrastructure is known as cloud monitoring. Websites, servers, applications, and other cloud infrastructure are checked for availability and performance using manual or automated management strategies.

Improved Cost Management

The public cloud host provides the necessary hardware for web servers, as well as security, maintenance, upgrades, and stack configuration. Many public cloud providers operate on a "pay as you go" basis. A data center’s price comprises more than simply your initial investment. Some cloud providers also offer autoscaling, that is, helping you to automate groups of resources. This autoscaling feature allows you to add numerous settings when needed. You can also turn them off when they are not needed. This cost-effective strategy can save even more money because you'll only be charged for the time those additional systems are on. Rather than needing to maintain additional equipment up and running all the time to deal with peak loads, this is an efficient system. As a direct consequence, your services can automatically respond with the number of resources mandated. This will help you to avoid both outages and unnecessary expenses at any particular time.

How To Prepare For Cloud Migration?

A large-scale cloud migration requires more meticulous preparation across the organization than migrating individual workloads to the cloud, which is very simple. A well-defined strategy is needed for successful cloud migration. Also, participation from key business, technical, and leadership stakeholders are the foundations of successful migration planning are of utmost importance.

Some notable cloud providers include:

  1. Amazon Web Services
  2. Microsoft Azure
  3. Google Cloud Platform
  4. Alibaba Cloud
  5. IBM
  6. Dell Technologies
  7. Hewlett Packard Enterprise
  8. Cisco Systems
  9. Oracle
  10. Salesforce
  11. SAP

What are some of the key areas to focus on while planning for cloud migration? Here are a few:

A. Security - If security isn't built in from the start, cloud migration might pose a serious security risk. The cloud's most significant benefit - data is available from anywhere, at any time. It is also its biggest weakness as it may be susceptible to various kinds of cyberattacks like hacking, data theft, etc. if not secured properly. On the bright side, the planning stage of a cloud migration project is the ideal opportunity to re-evaluate current IT and operational security in order to guarantee that the new platform is as secure as feasible.

B. Work on your budget - When you are looking forward to cloud migration, make sure you have enough money set out. Make sure you've factored in one-time and recurring software licensing expenses, as well as maintenance fees, migration tool prices, external contractors, and, of course, the costs of the public or private cloud infrastructure. To ensure that your future cost forecasting needs are as precise as possible, understand how costs scale as your workload or user count grows.

C. Examine your data fields' mapping - You'll need to map fields/tables from the old database to the new one unless your new program is an upgrade of an on-premise product going directly to its cloud equivalent. It's possible that this should be outsourced to professionals who have done similar work before.

Ending Note

If there is one thing technology has taught us - it is that data is the most crucial asset in today’s world. With cloud migration, you can safely store, access and manipulate that data according to your needs, even remotely. Cloud migrations have various advantages for both your company and your customers. It's also worth thinking about moving to the cloud as an opportunity to take advantage of new software capabilities. The cloud often contains sophisticated time-saving features that your on-premise software may sometimes lack. Don’t judge it before you even try it!
