If you want your business to be a part of digital transformation, then migrating it to the cloud is the first step. Many businesses have migrated to the cloud, leveraging its immense benefits of pay-per-go resource utilization and reduced cost.

Then what is stopping you from being a part of it?

You will be amazed that the cloud migration market is growing with the global adoption of digital transformation. Cloud migration services were valued at USD 9.22 Billion in 2020 and are estimated to grow to USD 49.96 Billion by 2028, growing at a CAGR of 23.52% from 2021 to 2028.

Isn’t it amazing how the world is getting digitalized with the simple adoption of cloud technologies? Suppose you have yet to migrate your business and apps and are struggling to migrate to the cloud. In that case, you have landed on the right page, as we have gathered all the necessary information to help you understand its long-term business benefits and concerns related to cloud migration.

So, let’s get you started.

But wait, are you clear with the core term “cloud” here?

Before you think of migration, you must be clear about what cloud means. Simply put, the cloud is cloud computing with a vast pool of resources, services, and others over the internet. To avail of these services (database, storage, applications, servers, etc.), you only need an internet connection without any specific setup.

Today, you will find several companies providing cloud services to others and even helping migrate their entire setup to the cloud with different plans. 

However, understanding your business requirements is necessary before you start migration, as the cloud offers different services, and you must know what services you want to help your business scale. You need to know what other cloud services are there so you can choose your plan wisely and reduce your IT spending.

Different Types of Cloud Computing

Cloud computing provides instant access to various computing services and resources online. This encompasses a range of applications, services, and servers, all stationed at remote data centers operated by cloud service providers.

Different types of cloud structures cater to distinct business needs. Let’s delve into the main types of cloud solutions to help you determine the best fit for your enterprise.

Public Cloud

These services are accessible to anyone via the Internet. They may be available at no cost or based on subscription or pay-as-you-go models. Cloud providers take on the responsibility of managing the data centers, hardware, and infrastructure, ensuring seamless operations for their users.

The public cloud market is anticipated to experience significant growth in 2022 thanks to its adaptability in accommodating fluctuating workloads.

It is a perfect fit for any business, so why do some companies opt for other options? If you have a scaling business that requires consistent resource demand, then the public cloud is not for you, as all the resources are shared over the network. If any other company exhausts all the help, it might be available at a different time, leaving your business to lose potential opportunities. 

This is why we have another option- Private cloud.

With a private cloud, businesses will get dedicated resources, overcoming the shared resources issue of the public cloud. In a private cloud, the virtual environment is split into different backgrounds for various businesses. 

Many businesses choose the private cloud as it is more secure and can have all resources dedicated to them to scale their business. 

But some businesses are on a significant level that need private and public cloud benefits, so they go for Hybrid Cloud.

For leveraging the benefits of both private and public cloud, Hybrid cloud is the better option for your business to scale efficiently. A hybrid cloud can connect your business’s private and public services into a single architecture so you can seamlessly run complex workloads. 

Also, the hybrid cloud allows your business to switch between private and public clouds per changing business needs. 

The core purpose of any business is to get necessary services within its budget. What if the company wants to avail of only some required assistance from a single cloud vendor as they get cheaper rates of a specific service from another vendor?

Of course, they want the best and cheapest services available. To accommodate such requests, multi-cloud and hybrid multi-cloud come to the rescue.

With the multi-cloud option, the cloud can avail services from different cloud vendors (Amazon, Oracle, Salesforce, and others), eliminating vendor lock-in situations. This is why it is popular among businesses as they get suitable services, such as IaaS, PaaS, and SaaS, at a reasonable price without sticking to a single vendor.

This helps businesses to migrate among the cloud and vendors efficiently. Some companies might be wondering what are IaaS, PaaS, and SaaS. Well, these are core cloud computing services that you will be available. Let’s understand them in the next section.

Cloud computing services 

The cloud offers unlimited services that are categorized into three categories- IaaS (Infrastructure-as-a-Service), PaaS (Platform-as-a-Service), and SaaS (Software-as-a-Service). 

Let’s understand in detail how availing of such services can help your business save high costs in the long term.

SaaS (Software-as-a-Service)

The cloud vendors host software on the cloud that companies can use directly. Anyone connected to that company network can use a good internet connection. It eliminates the need to physically install the software on each system on the company’s network. All you need is to pay as per your business requirement. 

The teams can access that software from any location or device with a single click. You know what is the next best thing- no technical support and maintenance of that software is on you. All is handled by the cloud vendor, from updating, upgrading, and troubleshooting that software. 

The software as a service (SAAS) market is expected to grow to $328.03 billion in 2027 at a CAGR of 6.6%.

PaaS (Platform-as-a-Service)

The cloud vendors will provide on-demand platforms that include hardware, software, entire tech stack, infrastructure, servers, networks, storage, database, operating system software, and middleware. 

It helps businesses to integrate different platforms without even managing their internal complexities. The cloud vendors will handle all the technical work so the company can focus on the core part. 

Seeing the benefits, many businesses are adopting cloud PaaS services. The platform-as-a-service (PaaS) market is projected to expand at a compound annual growth rate (CAGR) of 26.42% from 2022 to 2027. An increase of approximately USD 80.82 billion in the market size is anticipated during this period.

IaaS (Infrastructure-as-a-Service)

Reasons to Migrate to the Cloud

Migrating to the cloud offers a variety of advantages for businesses and individuals alike. Here are the core benefits.

  • Cost Efficiency

Traditional IT infrastructure requires significant capital investment in hardware, software, and the physical space to house it. There are also ongoing costs for maintenance, energy, and hardware upgrades. With cloud computing, you typically operate on a pay-as-you-go model, allowing for predictable operational expenses and eliminating the need for hefty upfront investments. Maintenance costs are often included in the subscription price, further reducing overhead.

 

  • Scalability & Flexibility

Traditional infrastructure might require a complete hardware overhaul to scale up. The cloud, on the other hand, allows businesses to adjust resources based on real-time needs quickly. This ensures that during peak periods, the system can handle the extra load while you’re not paying for unused resources during off-peak times.

 

  • Disaster Recovery

Cloud providers typically have data centers in multiple locations. This redundancy means if one center faces an issue, your data can be quickly recovered from another area. This robust backup and disaster recovery solution would be costly and complex to implement on-premises.

 

  • Automatic Updates

Cloud providers take care of routine software and security updates, ensuring all users have access to the latest features and are protected from known vulnerabilities. This removes the burden and potential human error from manual updates.

 

  • Remote Access

The cloud facilitates a modern mobile workforce. Employees can access their work from home, during travel, or at client locations, improving productivity and flexibility.

 

  • Collaboration Efficiency

Cloud platforms often include collaboration tools that allow multiple team members to work on documents or projects in real-time. This boosts team efficiency and ensures everyone is on the same page.

 

  • Security

Cloud providers invest heavily in state-of-the-art security protocols. This includes encryption during transmission and while at rest, multi-factor authentication, and regular security audits.

While no system can be 100% secure, the expertise and resources of major cloud providers often exceed what a single organization can muster.

 

  • Resource Management

Managed cloud services relieve businesses from the technicalities of daily IT operations. This allows companies to focus on their core competencies instead of getting bogged down in IT challenges.

 

  • Competitiveness

With cloud platforms, small and medium-sized businesses can access sophisticated technology without a massive investment, allowing them to compete more effectively with larger corporations. This democratization of technology can be a game-changer in many industries.

These benefits are tempting for any business to consider cloud migration. If you know that migrating your business to the cloud will reduce your workload, reduce cost, enhance security, and much more, why should you not do it?

But the question arises- migrating to the cloud as easy as it sounds. It can be complex, but the right cloud migration partner can make it easy for you and handle all the complexities. 

To understand the process of migration. How it works and what challenges you can face during migration.

Is Migrating to the cloud easy?

Moving to the cloud can be smooth if you plan well and understand your business needs. The cloud provider will handle the technical parts for you.

It’s essential to pick the right cloud partner. You might only get the desired results if you plan well.

Before migrating, ask yourself-

  • Where are you moving to?
  • Why are you making the move?
  • How will you do it?

Cloud Migration Process

It’s a good idea to have a checklist for your cloud migration. This way, you can track what’s done and what’s left, ensuring you keep all the data and avoid potential problems.

Here’s a simplified process-

  • Know your purpose of migration- Understand why you’re moving to the cloud. Everyone in your team, especially decision-makers, should know the benefits and reasons for the move.
  • Decide What and How to Move- Get to know the cloud you’re moving to. Figure out which applications you’ll transfer, any related dependencies, and the tools you’ll need.
  • Start the Migration- Begin with more straightforward tasks. Once you’ve moved, test your applications to ensure they work well and address any issues.

In short, a clear plan and understanding can make your cloud journey smooth and effective. Several migration strategies depend on your business situation. Let’s understand those strategies and choose the right one for your business.

The 6 Rs of Cloud Migration (strategies) 

These popular 6R cloud migration strategies will fit all your business needs. You can help you choose the right one after understanding them in detail. With the right approach, your migration will be more feasible and accessible. 

These strategies have been popularized by AWS (Amazon Web Services) but apply to any cloud migration effort.

Rehost (“Lift and Shift”)

rehost

This involves moving applications and data directly from the on-premises data center to the cloud without any modifications. It’s the quickest method but may only partially exploit cloud-native features.

Picture just lifting your entire room and placing it in a new house—no changes, no fuss. This is a straight move, and it’s fast. But, like when moving homes, sometimes you wish you’d rearranged a bit.

Replatform (“Lift, Tinker and Shift”)

replatform

This approach involves making a few cloud optimizations to realize a tangible benefit without changing the core application architecture. An example might be moving a database to a cloud-based managed database service. 

Think of this as packing your stuff but getting a shiny new cupboard at the new place. You’re not changing everything but making a few tweaks to fit better.

Repurchase (The “New Start”)

This involves moving to a different product or service, often shifting to a cloud-native solution. A typical scenario is changing from a traditional CRM to a SaaS platform like Salesforce. Have you ever felt like leaving behind the old and starting afresh? This is your chance to switch to a brand-new set, like swapping out that old couch for a modern sectional.

Refactor / Re-architect (The “Home Makeover”)

re-architect

This is about reimagining how an application is architected and developed using cloud-native features. It’s the most involved strategy and is often undertaken to add scalability, flexibility, or other cloud-specific benefits.

Imagine redesigning your room in the new house entirely. This is for those looking for a fresh, modern vibe, taking advantage of the latest home decor – or, in this case, cutting-edge cloud features!

Retire (The “Declutter”)

retire

Identify IT assets that are no longer useful and can be turned off. This helps save costs and reduces the complexity of migration. If you’ve got stuff you no longer need, why take it with you? This is the Marie Kondo method – if it doesn’t “spark joy” (or isn’t helpful), leave it behind.

Retain (The “Not Now”)

retain

Not all applications will be migrated immediately. Some might be kept in their current state for various reasons, such as an impending phase-out or regulatory constraints. The idea is to keep these applications and data in the current environment without migrating them.

Some items have sentimental value or might be needed later. So, for now, they remain where they are. It’s okay; we all have those pieces we’re not ready to part with or move.

Challenges during Cloud Migration

It can be challenging if you are migrating your business from traditional architecture. Sometimes, it includes developing an entire system from scratch. Not only this, there are a few list of challenges that any business can face despite full-proof understanding.

  • System Outages 

During the migration, there might be times when your local servers need to be paused. This can impact how well your applications run and test the patience of your loyal customers. It’s essential to have robust backups and proper resource planning to prevent significant disruptions.

 

  • Risk of Data Compromise 

When transitioning to the cloud, your data can be especially exposed. There might be moments when specific data is inaccessible or prone to security threats. Enhancing protection during this phase is critical, employing measures like advanced access controls and ensuring data encryption.

 

  • Adjusting to the New Environment 

Some IT staff might be wary of the cloud, having been accustomed to traditional server management. Adapting to the cloud might mean retraining some team members or reshaping specific IT roles. This transformation can also touch on the fundamental processes of your business operations.

 

  • Ensuring Seamless Communication 

Marrying your existing applications with the new cloud setting can be a challenge. To maintain smooth system interoperability, it’s crucial to tweak and align your procedures with your cloud provider’s environment.
