The 5 Biggest Benefits of Migrating From On Premises to the Cloud

Discover how migrating to the cloud can increase scalability and flexibility while reducing costs

The cloud isn’t just the future — numerous startups and legacy businesses are embracing the power and scalability of the cloud, right now. This shift is happening so rapidly that the average company will spend $8 out of $10 of its IT hosting budget on the cloud by 2024.

However, beginning an on premises to cloud migration is a difficult decision for many organizations that have spent decades investing in physical infrastructure, and it’s crucial to weigh the pros and cons. To help, we’ve compiled a list of the most significant benefits for businesses that migrate to the cloud, along with some success stories from organizations that made the leap. Read on to learn more.

What Is On Premises to Cloud Migration?

On premises to cloud migration is the process by which organizations transfer data storage and applications from on-site physical servers to public cloud data centers like AWS, Azure, and Google Cloud.

There are a few ways to successfully process a physical mainframe to cloud migration of data, and choosing the proper method largely depends on how much data organizations need to transfer. Organizations may opt for a differential copy if the volume of data is manageable enough to be transferred over the internet. Here, data is copied to the cloud while the application runs, either through a series of differential backups or a secondary database replicated in the cloud. In either case, once the team has transferred enough data to the cloud, engineers can decommission the physical servers and allow the cloud server to run in their place.

Organizations with data that is too large for internet transfer will need to opt for an offline copy. This process involves internal data transfer to a physical device, which the organization ships to the cloud provider, who then manually transfers the data to the cloud server. Once complete, the cloud server will run in place of the on-prem server.

In addition to data migration, teams may need to  transition entire applications and the infrastructure supporting them into cloud environments. There are a few strategies for application migration, depending on complexity or the required timeline to go-live. Organizations that need to get programs up and running quickly and at low cost may want to implement a lift-and-shift strategy, where virtual machines within the cloud run legacy applications without needing a significant overhaul. If you need to take advantage of cloud-native services, developers may need to refactor the application to take advantage of those features, which will require rewriting portions of code to run. In some cases, it may be necessary to decommission the legacy application entirely, as features may be duplicated elsewhere within the cloud, or it becomes more time-consuming or costly to refactor than writing a new application.

The Benefits of Cloud Migration

Cloud migration is not an insignificant task, and requires a keen understanding of the planning challenges and cost associated with making the move. Once finished, organizations will immediately start seeing cloud migration benefits to their operations and workflow.

Scalability and flexibility

Spinning up additional cloud resources is much easier, faster, and more cost-effective than building additional physical servers. Cloud servers can be added or decommissioned on the fly based on natural traffic demands, so you’re only operating with exactly what you need at all times.

Cost reduction

Since the cloud handles all of the work, there’s no need to maintain expensive on-prem hardware or pay power and maintenance costs to keep them operating. Organizations only pay for the resources they use.

Improved performance 

Splitting data across the cloud within multiple regional data centers makes it much easier and faster to serve a global audience than keeping data tied to a single physical location. And because it’s much easier to spin up load balancing servers to meet demand, users will be far less likely to experience downtime.

Automated security and compliance 

While it’s possible for on-prem security to meet or exceed the security found on cloud services, maintaining the team and infrastructure to do so is time-consuming and cost-prohibitive for all but the largest enterprises. 

Instead, services like AWS, Azure, and Google Cloud apply security and compliance best practices on the server side, which ensure the infrastructure is always covered. While organizations are still responsible for maintaining security within the cloud, they’ll have access to built-in features to help monitor data risk and manage IAM profiles.

Simplified and reliable resource management

Cloud platforms provide a central interface for accessing many of their features, making managing data management and reporting much easier. Included backup and recovery tools allow organizations to revert to prior working instances to reduce downtime rapidly. Plus, many services advertise a guaranteed 99% uptime, so organizations can be sure operations are stable.

Security Concerns During Cloud Migration

On-prem to cloud migration is a complex process with many moving parts, and teams must take proper care to avoid introducing security risks. Before beginning the migration process, create a plan and stay aware of potential exposure points to maintain data integrity during the transition. Here are a few concerns teams will need to consider before they begin:

  • Misconfiguration: Cloud platforms contain an array of settings, and inexperienced users may leave sensitive data exposed by activating improper configurations. Ensure the entire migration team reads and understands all documentation, and lean on expert advice and assistance when unsure how certain settings are meant to operate.
  • Improper IAM: Understanding how to set up least-privilege access roles and identity policies is important, as weak or improperly secure user accounts are often an attack vector for malicious actors during a cloud migration.
  • Transferring sensitive data first: It’s tempting to transfer the most important or sensitive data first to ensure a successful migration, but this is the period where teams are least experienced with new platforms and may introduce an unnecessary risk of data exposure. Teams should get familiar with the cloud by working with common, non-critical data and only transfer sensitive data once they are fully confident in the platform and how it works.

Cloud Migration Success Stories

Successful businesses that switch to cloud data services often cite the migration to the cloud as one of the key factors of their success.

Take Airbnb, a community-driven vacation rental hub that connects millions of travelers with hosts in over 100,000 cities across the globe. The company was formed in 2008 but quickly realized it needed a cloud solution to manage its data. A year later, leadership migrated operations to AWS, completing the entire database migration with a five-person operations team and only 15 minutes of downtime. Airbnb was then able to seamlessly scale up its operation, adding additional servers as its business grew.

Auto Trader also made the jump to the cloud in recent years. The UK-based print magazine-turned-digital automotive marketplace transitioned to a digital business model in 2013 but still managed on prem infrastructure with an Oracle database. In 2018, the company decided to transition to Google Cloud SQL. As of 2021, it has migrated around 65% of its database to the cloud. This transition has allowed its teams more flexibility in development, making maintenance easier to manage for developers and users, as well as the ability to provision instances for work without disrupting the main product.
