Let’s go down memory lane!

It's a Saturday evening in 2012 and your friends have joined you for a lazy gaming session. At the last minute, you realize the game needs to download 15 GB of assets to the computer - but it has 5 GB of available space.

You wonder why your storage is so full. Well, it's crammed with college assignments, academic PDFs, photos of your cats and even your favorite movies. (We must have the Stuart Little movies ready to go on every device!) 

Back then, the options were a 4 GB pen drive or maybe an SD card that wasn't even compatible with a smartphone. Feeling nostalgic yet? It's more than nostalgia; it's a nightmare!

You see, we have a hundred modern solutions to store our vast data. While we individually might have tens of gigabytes, businesses have much more massive amounts of information and may face situations where they need to migrate their databases from one

They can't just plug in a 1 TB hard drive and move everything – such as migration requires strategic planning and technical skills. That's what we'll be discussing in this article: Cloud Migration - and its top strategies, benefits and challenges you need to know. Let's dive in!

Quick question: can you name five applications installed on your mobile that run on the cloud?

While we may not realize it, most online applications today operate on the cloud. This means the application, its storage, operations and servers are hosted on the cloud, instead of functioning on your local mobile like a calculator app might.

Everyone's migrating to the cloud now as it has become a necessity for businesses. A survey by Flexera found that 58% of technical professionals place a high priority on moving workloads into the cloud and 39% are already working toward a cloud-first strategy.

So, what does Cloud Migration mean? To put it simply, it's when you move your data and applications into a cloud-based platform. However, the definition is slightly more complicated when you think about the details of migrating your data. It involves different strategies with benefits and challenges.
Before we get into them, let’s first understand Cloud Migration closely.

What Is Cloud Migration?

Cloud Migration is the process of a company moving all or part of its data, applications and workloads from on-premises servers to cloud-based platforms with the help of cloud service providers like Microsoft Azure or Amazon Web Services. This means the data and applications can be accessed from anywhere rather than being hosted by an on-site server connected to on-site computers. Now, you know how you can access Instagram from anywhere!

Cloud Migration typically involves four main stages: assessment, planning, migration and optimization. First, you evaluate your current infrastructure and identify the applications and data suitable for the migration. Next, you create a detailed migration plan with timelines, budgets and resource allocation. Then, you move your applications and data to the cloud. Finally, you fine-tune your cloud infrastructure to ensure the best performance. #MigrationMadeSimple

You see, Cloud Migration lets organizations leverage the scalability, flexibility and cost-effectiveness of cloud computing. However, there are different strategies based on your business requirements. Let’s understand them!

Cloud Migration Strategies

When it comes to Cloud Migration, organizations can choose from seven different strategies, known as the "Seven Rs." Each migration approach offers its own advantages and considerations, such as:
  • Rehosting (Lift and Shift)

    This strategy involves moving applications from on-premises to the cloud without making any code changes, using Infrastructure-as-a-Service (IaaS). It's simple to implement and suitable for organizations unfamiliar with cloud systems.

  • Relocate

    While it’s quite similar to rehosting, this strategy involves moving applications from one cloud platform to another without making significant changes.

  • Refactoring

    This method involves completely rewriting the existing workload to be cloud native. While it requires time and skills, it offers the best cloud benefits in terms of scalability, performance and cost-effectiveness.

  • Replatforming (Lift and Reshape)

    This approach allows organizations to make some modern changes to existing applications, such as scaling or automation, without completely replacing them. It's a middle ground between rehosting and refactoring.

  • Repurchasing

    In this approach, organizations replace their existing applications with cloud-based Software-as-a-Service (SaaS) solutions, essentially outsourcing the application management to a third-party provider.

  • Retiring

    This strategy involves decommissioning legacy applications or systems that are no longer needed, freeing up resources and reducing the data that needs to be migrated.

  • Retaining

    For some organizations, cloud adoption may not make sense due to regulatory concerns or other factors. In such cases, they can choose to retain specific applications on-premises until a later date.

Each migration strategy has its own advantages and considerations and organizations often employ a combination of these approaches based on their specific requirements, budget and existing infrastructure. Here are the top benefits!

Benefits Of Cloud Migration

Here are the main benefits of Cloud Migration:
  • Optimized Costs

    Cloud Migration can lead to significant cost savings by eliminating the on-premises hardware, maintenance and real estate expenses. With pay-as-you-go, you can optimize workloads and make a cost-effective infrastructure.

  • Flexibility And Scalability

    With cloud computing, you can easily scale your computing resources up or down based on demand. Also, there is no need to pay for unused capacity or face a lack of resources during peak hours. That's how the Amazon ecommerce website runs smoothly, even during festivals and peak discount seasons!

  • Improved Security

    Cloud platforms offer built-in security measures at the platform level, which can help organizations better protect their data and applications. No more in-house security hassles!

  • Compliance

    For highly regulated industries like finance, healthcare and government, some cloud platforms also offer cloud compliance. This simplifies the process of adhering to industry-specific regulations and standards. That’s a relief, isn’t it?

  • Backup, Recovery And Failover

    Most cloud providers offer built-in backup, recovery and failover capabilities, including the ability to store backups in different geographic regions.

Improved business continuity and minimize downtime? Sounds like a win-win!

Through these benefits, organizations can enjoy streamlined operations, reduced costs and improved security and compliance. However, there can be some challenges to be aware of before starting any cloud migration journey.

After all, it's understanding the challenges that will help you grow and improve!

Challenges Of Cloud Migration

You see, a coin always has two sides. When you are running a business, you must similarly consider the potential hurdles of any technology – and Cloud Migration is no exception. Some of the critical challenges associated with Cloud Migration include:
  • Planning

    While migrating individual workloads can be straightforward, planning a large-scale Cloud Migration requires a well-planned strategy. It involves assessing the current infrastructure, identifying suitable applications and data for migration and eventually developing a detailed roadmap for the migration.

  • Cost

    Although Cloud Migration can provide significant cost savings in the long run, it involves upfront costs. Organizations must carefully evaluate the total cost of ownership and ensure that the migration aligns with their budgets.

  • Security & Compliance

    Cloud providers offer a range of security and compliance settings but organizations are ultimately responsible for implementing the solution that meets their requirements. Organizations must configure security settings, establish access controls and ensure compliance with industry-specific regulations.

  • Business Downtime

    While modern cloud platforms allow for rapid data migration, there can be downtime during the migration. Organizations must think of plan B to ensure business continuity and avoid disruptions to critical operations.

  • Organizational Adoption & Training

    While most existing IT skills are applicable to cloud environments, some level of training and upskilling may be required for IT professionals and developers. It gets easy but requires practice and training.

By proactively addressing these challenges and developing comprehensive migration strategies, organizations can mitigate risks, streamline the migration process and maximize the benefits of cloud computing. On that note, let’s conclude this article!

Final Words

In today's time, having your data or applications on the cloud is a necessity. It not only frees us from physical storage limits but also lets us access our stuff from anywhere. Even though moving data to the cloud can be tricky, the benefits of the cloud, such as easy scaling, cost savings and better security, make it worth it.

As we wave goodbye to the old days of running out of storage space and welcome the cloud's endless possibilities, let’s hope that data migration also becomes as easy and fun as cloud computing itself!
Before we say goodbye, a thought to ponder upon:
