Cloud Migration Strategies, Process, and Tools: The Ultimate Guide

According to Cybersecurity Ventures, more than 100 Zettabytes of data will be stored in cloud data centres and worth USD 448.34 billion by 2025. These numbers demonstrate how the cloud market will expand in the coming years.

Success in the current digital world requires embracing the power of the cloud, particularly as businesses increasingly move their apps to the cloud to spur growth.

WebTribunal Cloud Migration reports that global spending on public cloud services will increase from $257.5 billion in 2022 to $623.3 billion in 2023. More than 45 per cent of IT investment will move from conventional solutions to cloud-based services by 2024.

Despite significant investments in the cloud, one in three businesses never reaps the rewards. According to the Unisys Cloud Success barometer survey, 33% of firms have experienced little to no improvement in organisational effectiveness since adopting the cloud. Moving to the cloud is a complex and expensive process. So how to avoid a cloud migration failure?

Planning effectively and choosing the best cloud migration strategy for your IT assets are the key to finding the solution, developing a path for migration, and making the switch to the cloud more easily.

Move your business elements, data, and applications to a cloud environment by choosing the most suitable cloud migration strategy. This guide covers everything you need to know about cloud migration as six cloud migration strategies, including their use cases, challenges, benefits, and best practices to ease your migration process in 2022.

Let’s get started with discovering what cloud migration is.

What is Cloud Migration?

Cloud migration is moving data and applications from on-premises architecture to the cloud. Not all workloads benefit from running on cloud-based infrastructure, so validating the most efficient way to prioritise and migrate applications before going live is essential. A systematic, documented strategy is crucial.

The journey to the cloud differs for every organisation, as there is no one-size-fits-all migration plan. Each IT asset to be migrated is unique in terms of cost, performance, and complexity. So you cannot move all components to the cloud with one standard method. The migration strategy will answer the questions of what, how, and in what order to move these components.

Most plans include a public cloud migration strategy where the target is Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, or other public cloud providers. Data centres are facilities devoted to housing computer equipment, as opposed to a server room or server closet, the storage units for computer systems you could find behind a locked door in any given office. They are typically enormous and built primarily to maintain a lot of technology functioning at its best.

What are the Main Benefits of Migrating to the Cloud?

The advantages of cloud computing are frequently centred on efficiency, getting the most out of resources while spending the least money. Organisations can deliver enhanced performance by choosing a cloud-based solution, staying up-to-date with technology innovations, and benefit from higher scalability, lower expenses, and security. Here are the main benefits of migrating to the cloud.

scalability

scalability is the power to rapidly increase or reduce computing, memory, and storage resources to satisfy changing demands without worrying about cloud capacity planning. A corporation can effectively scale its IT requirements up or down depending on its current needs by migrating to cloud platforms.

By moving to the cloud, organisations are no longer limited to swiftly degrading equipment and can significantly adjust their operations and architecture to accommodate current demands.

Cloud computing is scale can scale up to support large workload and more significant number of user far more quickly than on – premise infrastructure , which require company to purchase and set up additional physical server , network equipment , or software license .

cost optimisation

accord to the Microsoft Office 365 report , 82 % of SMBs account reduce costs is reinvest due to cloud technology , and 70 % is reinvest reinvest the save money into their company .

Thanks to the cloud, you can only pay for the resources you utilise. It allows you access to resources that would be far too expensive and time-consuming for you to maintain on your own, which is related to scalability. Companies can allocate more resources to their business needs, such as creating new goods or upgrading their current ones, rather than maintaining operations.

The top initiative is optimising mention by enterprise is optimise the current usage of the cloud ( cost saving ) , follow by move additional workload to the cloud . workload migration is increase may increase agility while reduce cost .

Remember that an organisation’s cloud spending can spiral out of control without an acceptable strategy!

Flexibility

Using the cloud also enables you to adapt to changing circumstances quickly. With a few mouse clicks, it is easy to access new services, making it feasible to act immediately when a new need, challenge, or opportunity arises. Users can access the cloud services and data they require from any location, whether they are clients or workers.

It facilitates a company’s ability to grow into new markets, provide its services to clients worldwide, and allow workers to work flexibly. Moreover, migrating to the cloud can improve performance and end-user experience.

Advanced Security

Cloud providers take care of security and compliance, which includes keeping up with upgrades and market trends to guarantee the protection of your sensitive data in the cloud.

Regularly releasing security upgrades prevents unauthorised users from accessing your data, allowing you to focus on what matters to your business without worrying about security risks.

The policies, technology, and controls that public cloud providers typically offer substantially improve the security procedures used by most organisations. Along with this, practically any industry-specific compliance requirements are taken into account.

additionally , store datum on the cloud rather than on your hard drive can prevent data breach if a device is lose or steal .

Discovery Recovery and Failure Processing

If something disastrous happen to their physical equipment , operations is stop wo n’t stop . Without the need for a team to be present , problem can be promptly discover and fix when these protocol are include in routine process .

Cloud providers offer easy ways to manage automated backup and recovery procedures, which promote company continuity. Further, they deliver built-in, user-friendly backup and recovery features, including the choice to store backups in various geographic locations.

Why do Businesses Migrate to the Cloud?

There are many reasons why companies move their operations to the cloud. However, working on the cloud offers you access to nearly infinite computing resources, which is a significant factor.

Following the report by BCG, cloud migrating may save businesses 15–40% on infrastructure expenditures, with the top three reasons being reduced IT costs, more agility and flexibility, and improved disaster recovery. For some businesses, savings might be considerably more significant.

A basic example is Clouds like electricity. A simple exercise compares this infinite supply of computing and storage to electricity.

• Yes, you could run a generator to generate electricity independently, but the hardware is expensive upfront.
• Then , you is maintain must maintain its functioning , which require a certain amount of knowledge and regular maintenance time .
• Unless you ’ve splurge and had a second generator lie around ready to go at a moment ’s notice , you is ’re ’re out of luck if it break down .

However , if you and those around you both require electricity , it is makes make more sense to outsource the setup and ongoing management of electricity generation . It is is is similar to how you consume electricity on daily basic . Then , with the flick of a switch , you is access and all your neighbour who require electricity can access it .

• You is are are free to use what you need and only pay for what you use .
• You are free to use as much electricity as they require.
• The electric utility will take care of you.
• They is concentrate concentrate on provide you with electricity fast and effectively , free you up to focus on what has to be done .

adopt a cloud migration strategy help your company to identify and execute the fast , low cost , most minor disruption transition from on – premise to the cloud .

Since every organisation is different, an enterprise cloud migration strategy should be tailored to their needs to achieve the desired business and technical outcomes. It requires knowledge of the business needs and goals and the application portfolio that can provide visibility for undertaking a migration.

What are the challenges is are of a cloud migration strategy ?

Migrating to the cloud does not come without obstacles. Transferring large databases is time-consuming and difficult. Sometimes companies will need to slowly move data across a long period before the on-premise system can be dismantled. Organisations must know what needs to be migrated and why, rather than jumping in with both feet and trying to shift every workload to the public cloud.

Among the critical situations to be aware of are:

Data security and compliance are two main barriers to cloud migration. The security of the infrastructure is handled by the cloud service provider, while the client is in charge of protecting data and workloads, data retention, and data privacy.

Therefore, even though the cloud provider might offer robust security measures, your firm is responsible for setting them up properly and ensuring that all services and apps have the proper security controls.

Cloud can result in cost savings; however, it can be challenging to estimate cloud costs. It’s simple to misjudge cloud costs. Not only should the relocation costs be taken into account, but also the costs of the migration services, the future need for more bandwidth, and future recurring expenditures.

Many firms is defined have not clearly define kpi to determine what they plan to spend or save after shift to the cloud . Because of this , it is challenging is challenge to determine whether migration was profitable . additionally , cloud environment are dynamic , expenses is are are subject to quick change when new service are adopt , and application demand increase .

• Keeping data safe during migration

Your company’s data is most exposed when transferred to the cloud. For large databases that would take too long to send over the Internet, some cloud providers provide physical data transfer techniques, such as loading data onto hardware equipment and delivering the appliance to the cloud provider. Application of cloud security controls like privileged access management and app encryption must be made with extreme caution to reduce the danger of a compromise.

Before creating your plan for cloud migration, we consider all of it to make your migration to the cloud with confidence.

How does a cloud migration strategy work?

Organizations should consider the design and requirements of each application before deciding on migration options, as well as the skills, resources, and timeline needed to achieve the desired results. To evaluate the maturity of each workload, teams must first assess what is already in place. For each instance of every application that is currently in use, this might necessitate a thorough discovery stage.

The workload migration process should be planned with milestones, distinct targets, appropriate timeframes for each activity, and an awareness of potential dangers.

Every migration is start should start with a pilot effort , perhaps relocate or rehosting . It is makes make it easy to spot any gap and make necessary adjustment .

The company should concentrate on three crucial areas of optimisation to carry out a migration at scale:

It’s crucial to evaluate your environment and identify the variables that will control the migration, such as critical application data, legacy data, and application interoperability. It’s also essential to assess your dependency on data: do you have non-critical data that might be transferred during the first few migration rounds.

• Migrating your apps and data

determine the operational gain , cost saving , and architectural improvement along the three dimension of the predict cloud migration benefit . In exchange for a long – term commitment to cloud resource or a commitment to a specified amount of cloud spending , cloud providers is provide provide a variety of pricing scheme and saving plan .

• Choosing your cloud environment:

Choose the cloud model you want to use now that you have the visibility you need to succeed. Depending on which best meets your immediate and long-term goals, you should select a public cloud, hybrid cloud, private cloud, or multi-cloud (or services like Google, Azure, or AWS). Just make sure your APM solution includes the provider you’ve chosen.

The 6 R’s of Cloud Migration Strategy

There are six types of cloud migration strategies. However, this does not mean that they are the only solutions. Your strategy should fulfil your needs and capabilities. Each cloud migration will be unique, and these strategies are not definitive. Use this guideline when you create a cloud migration strategy.

A cloud migration project can easily include elements of all or some of these strategies at different stages:

• Rehost — known as “lift-and-shift.”

The easiest method of cloud migration is rehosting. It entails transferring software, virtual machines, and server operating systems unchanged from the current hosting environment to public cloud infrastructure.

If you decide to adopt lift-and-shift, you should be aware that it has a short-term downside: limited utilisation of cloud efficiency. Cloud-native features, such as monitoring systems, automated recovery, self-healing, or open-source compatible services, are not operated merely moving an application burden to the public cloud. You will be able to reduce the time spent on system management and free up some time so that engineers may once again concentrate on resolving business issues and product optimisation.

When businesses need to change their on-premise infrastructure quickly, this cloud migration can also serve as the beginning point for large-scale optimisation projects. For instance, if your data centre lease is about to expire, you could need to rehost your current workloads swiftly. Further codebase optimisations will be more straightforward once these workloads are in the cloud.

The move – and – improve strategy is updating for migration is update your program with contemporary feature , such as scale or automation , without completely replace it . The strategy is appear may first appear to be the good choice , but it may lead to migration where you retain all of your technical debt and receive none of the advantage of cloud – native development .

This strategy entails starting over your workload to make it “cloud-native.” It requires time and skill development (especially upskilling your current talent), but it pays off with the most significant cloud benefits.

While every business and workload is different , if your goal in shift to the cloud is to profit from its unique feature and advantage , you is adopt should adopt cloud – native design principle . It is entails entail plan and doing thing correctly , include ensure your staff is equip to handle the transition and rewrite your code .

• Repurchase — moving to a different product.

This strategy means moving your applications to a new, cloud-native product, most commonly a SaaS platform (for example, a CRM to Salesforce). The challenge is losing the familiarity with existing code and training your team on the new platform. Repurchasing might be your most cost-effective option if moving from a highly customised legacy landscape.

It relates to the decision made by the company to switch to a different product, which occasionally entails terminating current licensing and repurposing services on a new platform or service. It is frequently unnecessary with apps created using modern application code because moving the code from one provider to another is unimportant.

Once you have disclosed everything in your explicit environment setup, finding out who is in charge of each functional area’s application is best. This method makes it simpler to obtain savings to strengthen the business case and focus the team’s scant attention on the team’s human resources. Additionally, the goal in this situation is to reduce the security’s visible perimeter.

• Retain — means “revisit” or do nothing (for now)

Last, we have kept it one of the best methods for moving applications to the cloud. There can come a time when you’re not prepared to give a recently enhanced application priority. Additionally, there’s a potential that you won’t want to move all of your applications. At this stage, the best course of action is to relocate only what is necessary for the business. You will have fewer reasons to hold on if you realise that the portfolio’s focus has shifted from on-premises to the cloud.

Migration Services + Tools

What program is employed for cloud migration? There are many more than one! Large public cloud providers like AWS, GCP, and Azure want you to migrate to their portion of the cloud; they provide you with many tools to make the process as easy as possible.

Moving to the cloud may result in cost reductions, but cloud costs can quickly spiral out of control. Using all the resources at your disposal to plan and modify procedures is crucial. Things that were cost-effective in-house can become costly errors in the cloud.

Before move , you is estimate can estimate the cost of your setup with the use of cloud cost calculator . examine the one that your public cloud provider provide . Examples is include include the Google Cloud Pricing Calculator , the AWS Pricing Calculator , and the Azure Pricing Calculator .

Other tools to look into are Microsoft Azure Advisor for Azure and AWS Trusted Advisor for AWS. These give you in-the-moment advice on best practices for the cloud and can also assist with cost reduction, cost optimisation, security, and performance.

accord to Canalys , the top three cloud service providers is accounted account for 62 % or US$ 55.9 billion of total cloud spending in the first quarter of 2022 .

Best Practices for a Successful Cloud migration

There are different technical processes and recommendations for moving different workloads and creating different cloud configurations, but this step-by-step guide can serve as a strong foundation:

Creating goals is a crucial phase that Has to be in every cloud migration strategy. The objectives of your cloud migration strategy should be formalised and recorded. When creating your migration plan, consider both the current infrastructure and business objectives, as well as a few technical details and key performance indicators (KPIs). The baseline for measuring cloud migration activity would be an ideal goal.

• Finalise which asset are move and when

By assess each investment in term of cost , performance , size , complexity , and internal dependency , this practice is allows — an essential component of the portfolio discovery and planning phase — allow you to understand the current environment well .

Afterwards, a business case and KPI metrics can be created using the evaluation to evaluate the performance of each asset both during and after transfer. Companies relocate the less-important components first and only move the important ones once the proper support infrastructure is in place. The chosen strategy must be used to create, migrate, and test new applications.

• Prepare your team and the existing IT environment for the transition

Working with cloud technology differs from working with in-house technology, particularly if a company is switching from traditional infrastructure to the cloud for the first time. To operate with a particular cloud provider, employees must receive training. Because there are ongoing updates, this training cannot be done once.

Additionally, you must prepare the current IT environment by strengthening the network connection, allocating resources, controlling access, and implementing a system for security, compliance, and governance.

• Select the right partner for your cloud migration journey

choose the right cloud vendor for the organisation is essential since this is a long – term relationship . select a cloud vendor depend on its current service and future technology roadmap . Your cloud provider is understand must understand cost , tool , compliance , security , governance , and cloud – skill requirement .

A formal business process is requires , a cloud migration is requires require documentation at each stage . The objectives is cost , resource , migration tactic employ , cost analysis , and testing and training plan should all be include in this documentation . All parties is use will use the document as a reference for compliance audits .

• Test and validate for optimisation

Use the same business objectives, and unique application KPIs specified during planning to assess and evaluate the migration’s success accurately. For instance, you can decide that a cloud-hosted version of an application that was first rehosted is necessary. The foundation might need to be improved as cloud workloads change over time. The strategy must include the testing timetable. After testing is complete, short- and long-term success must be evaluated using the KPIs established during the goal-setting phase.

The cloud computing ecosystem is evolving quickly, and changes are ongoing. Many cloud services are uncontrollable “black boxes,” with very few controls that the company may override. Automation streamlines the process, shortens downtime, and frees your team to work on other crucial activities.

Conclusion

A cloud migration strategy requires careful planning, testing, and resourcing. The stakes are high when a cloud migration process kicks off. Both business and operations need to be secure from the get-go. A good cloud migration strategy needs to ensure that this aspect is taken care of and that the organisation leverages the cutting-edge technology of the cloud to stream ahead.
