As digital technologies are evolving, more companies prefer cloud platforms for their on-demand resources. The cloud computing landscape is fast-paced and dynamic. Its strategies offer a roadmap enabling brands to identify the best approach to transfer applications and data to the cloud.

Cloud migration provides significant benefits, but you may encounter roadblocks without a concrete strategy in place. These include high cost, compliance risk, and elaborate migration.   Awareness of the types of cloud migration and the steps involved will promote a smooth transition from on-premise to remote servers.  

We’re kicking off this blog with an in-depth discussion of cloud migration, followed by its types, steps, and tools. This compilation will guide you to successfully integrate a cloud and move all data to this platform without glitches.

Cloud Migration Process

A cloud migration strategy comprises a variety of services, databases, IT resources, and applications. It refers to the plan a company designs for moving data and applications from on-premises to a cloud infrastructure. A systematic and documented migration strategy will ensure an efficient migration.

Let’s take a look at the types of strategies for data transfer.

Strategies to transfer into the Cloud: The 7 R’s

When migrating to the cloud environment, you can choose from seven strategies. Gartner originally referred to them as the 5 Rs, which later expanded to 7 Rs.  Here’s a brief about each:

Refactor/Re-architect

You can transform an application by modifying its architecture and incorporating cloud-based features. This cloud migration strategy provides more agility, better performance, and enhanced scalability. With refactor migration, you can port the operating system and database hassle-free.

Replatform

When you opt for the replatform strategy, it allows the transfer of an application to the cloud while using optimization to leverage cloud-native capabilities. The source code and core architecture remain intact, and the legacy applications are operational. With replatform migration, you can experience heightened flexibility, agility, and resilience along with automation. It conserves your time and resources while allowing you to select components for modernization.

Repurchase

This migration strategy allows you to swap the internally administered systems for third-party managed services accessible in the cloud environment. This enables you to retire legacy systems and upgrade to a SaaS subscription model. As and when the services increase and third-party vendors get involved, this model seamlessly manages operations for in-house teams. The migration process gets expedited while reducing downtime and enhancing scalability. It applies to workloads requiring enhanced application performance/ user experience and minimal operational heads.

Rehost

The rehost migration utilizes cloud infrastructure as a service (IaaS) that retains the core infrastructure of the application. Also known as the Lift & Shift strategy, it enables the migration of an application to the cloud without making any changes to use the platform’s features. With this, you can transfer all data and workflows to relevant cloud networks. It ensures alignment between the existing storage, networking, and computer requirements between on-prem and cloud services.

Relocate

Relocate the infrastructure to the cloud without any new hardware, application rewrites, or impacting the current operations. When you use this strategy, you can migrate a collection of servers from an on-premise platform to a cloud version of the same server. You can experience minimum downtime and disruption, reducing the need to retrain staff or invest in upgraded hardware.

Retain

Some applications cannot be retired, so they remain operational in the existing framework. Retain cloud migration strategy is best fitted for such apps. Businesses choose to retain a workload when they rely on other applications to be migrated first.

Retire

As the name suggests, utilize this strategy to discontinue any application not required in the source network. You can implement a retire migration when terminating or downsizing applications that do not add much value.

Benefits of Cloud Computing Migration 

Here’s a list of reasons to migrate resources to the cloud.  

Scalable

In traditional IT environments, companies will buy physical server software licenses and set up a network system. With a cloud network, you can easily scale your brand with the capacity to handle large workloads and more users.

Cost-effective

With cloud computing, you can access managed services that reduce operational overhead, thus simplifying maintenance tasks such as upgrades. When you migrate to a cloud environment, you invest less in finance as compared to IT operations. This allows you to allocate more resources to innovating new products or improving the existing ones.

Performance

One of the pros of cloud migration is performance improvement and better end-user experience. When you host applications and websites on the cloud, you can scale up and serve more users. What’s more— you can run and access from various global locations near end-users. In this way, you experience an enhanced overall performance efficiency.

Digital experience

The key highlight of the cloud network is secured accessibility from anywhere. This applies to employees as well as customers. A cloud contributes to a better digital experience, thus providing modern and flexible tools.

Steps for An Effective Cloud Migration Strategy

Cloud migration spans five key stages: preparation, planning, migration, operation, and optimization. Let’s dive into each of these in more detail.

Preparation

Before designing a cloud migration plan, consider your brand’s unique infrastructure demands. In this phase, analyze the existing framework, its strengths, and loopholes, and identify your needs. Once you have determined this aspect, you can work towards ensuring the cloud meets your requirements. Involve your potential cloud service partner experts, cybersecurity associates, and IT team to assess cloud migration priorities.

Planning the migration

Before diving into the process, define the reasons for migration and which strategy is best-fitted. This stage involves assessing the current legacy infrastructure and the existing resources and expertise. It provides clarity on the ideal cloud solution for your business. Along with your migration team and cloud services partner, select the cloud model, vendor, and the nitty-gritty of the migration process. Decide whether you want to adopt a private cloud or hybrid, or opt for multi-cloud services like Azure, AWS, or Google.

Migration

Once you have done your analysis, the next step is to implement the decision and migrate to the selected infrastructure. However, despite all rigorous planning and preparation, the process could sail smoothly, or there could be hiccups. It is a good idea to keep a data backup and recovery option.

Operation

It is tough to say whether or not a cloud migration was successful without evidence that it is working as expected. Going live is one way to find out. There is more to this step than merely announcing the ‘live launch’ of the cloud environment. You need to prepare well for the go-live event.

Begin with a data freeze —before going live, halt all changes to your legacy environment and perform a final data sync.  From here on, record any changes made to the going-live process and synchronize after. A trial go-live can also be considered if you have the time and capacity. And most importantly, have a plan B to lean on if any unexpected issues arise or the go-live takes much longer than anticipated.

Ongoing support

When you use the cloud, you will need a support framework to keep you going. The ongoing assistance will offer maintenance and monitoring strategies to promote cloud success. You need to review updates at least monthly and go through software updates periodically. Also, you will benefit from consistent performance monitoring in place, providing the relevant tools for monitoring. This would have an added benefit, especially if your brand does not have a dedicated migration architect.

Cloud Migration Tools

Believe it or not, integrating with the right tools can make a huge difference. Cloud migration tools can benefit businesses by providing diverse solutions. Some may be specific to major cloud platforms like AWS, Azure, OR Google Cloud. And others are likely to be compatible with migration to a series of cloud providers. Whether you are running a small business or a large corporation, an in-depth knowledge of these tools will support informed decision-making for a smooth cloud transition.

There are many advantages of using the cloud, including compatibility with different software and a seamless experience altogether. With cloud migration, you can shift business data and applications to an online server. Although beneficial, it is a complex process involving informed decision-making. You need to select the right application between the 7 R’s. And the choice will depend on several factors like hardware requirements, scalability and availability, technical compatibility with cloud infrastructure, your business goals, and budget constraints. With plan and precision, you are sure to develop a robust cloud migration strategy.

Understanding Cloud Infrastructure: All You Need to Know

With the surge in digital transformation, the cloud infrastructure market promises substantial growth. How can business leaders leverage it for their organization’s benefit?

Cloud infrastructure consists of all the hardware and software needed to execute and support the delivery of cloud services to customers. The cloud has become an omnipresent force in the modern computing domain. According to Gartner, worldwide end-user spending on public cloud services is expected to reach $675.4 billion in 2024, up from $561 billion in 2023. This growth is attributed to generative AI (GenAI) and application modernization.

Today, when the world is filled, or rather fuelled, by tech-savvy people, cloud computing infrastructure gives them the agility to digitalize core components of their business operations without spending excessive money on on-premise hardware. It also helps when the hybrid work culture is gaining popularity. The shift to the cloud can give employees access to apps from anywhere in the world – basically bringing the concept of workations a reality.

Types of Cloud Architecture

Cloud infrastructure does not rely entirely on third-party, public cloud service providers. The three widely adopted cloud architecture models use the same primary elements of cloud infrastructure to deliver computing services.

Private cloud architecture

model, only one organization can access the cloud infrastructure. The private cloud infrastructure could be developed in-house by on-site IT staff, or it can be delivered by an external service provider.

Public cloud

includes third-party providers offering cloud resources to paying customers over the Internet. Public cloud providers use a multi-tenant environment model to lower the cost of computing power and data storage for their customers. The multi-tenant environment lowers the overall cost of computing resources, but it may also create privacy concerns for companies dealing with sensitive data.

hybrid cloud

computing model is defined as private and public cloud systems integrating in a separate but connected system. Organizations that deal with sensitive data may opt for maintaining data privacy by storing sensitive information in their on-site servers while hosting less sensitive applications and other resources in the public cloud where the costs are lower. Organizations that use hybrid cloud maintain their confidential cloud environments but may utilize public cloud services for added capacity or computing tasks on a flexible basis.

Three Cloud Infrastructure Delivery Models

Cloud service providers deliver cloud infrastructure and related services in three main delivery models: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS). These delivery models differ by the parts of the technology stack that are outsourced.

IaaS model

a cloud service provider delivers networking, data storage, servers, and virtualization capabilities. The customer earns access to unlimited data storage and computing power, but they must have their own software platform to run on it. The software platform includes operating systems, runtime, middleware, data, and applications.

PaaS model

a cloud service provider supplies the cloud infrastructure, including networks, servers, data, and virtualization, along with a software platform comprising operating systems, middleware, and runtime. The PaaS model provides customers with the capability to develop, test, deploy, and execute their own applications in the cloud without the usual expense and intricacy of building on-site IT infrastructure.

SaaS model

a service provider delivers an application via a web-based portal, removing the need to store any information about the application on a local hard disk. The entire data storage is located on the servers of the service provider. SaaS companies are reliable for every element of the tech stack – from upholding the cloud infrastructure that supports the application to the application itself.

Cloud Infrastructure Components

Storage

Cloud storage stores data, gives you access to the latest version of a file and its previous versions, and stimulates remote access as required. It is a virtual storage – it enables people and organizations to access, edit, store, and backup their data from anywhere and anytime. There are three primary cloud storage models:

• Block storage—segments and stores data into blocks instead of complete files. It is perfect for storing static data that does not need to change regularly.
• File storage—like the file manager systems operated with regular PCs.
• Object storage—suited for storing unstructured data or data that needs frequent modifications.

Virtualization

Virtualization means creating a virtual version of a physical machine. It adds a separate machine layer that allows multiple virtual machines to run on a single physical machine. It reduces hardware costs, improves scalability, and provides better security.

Network

A network in cloud computing infrastructure is a bunch of interconnected computers and devices used to share resources and data. Cloud computing networks can be private, public, or hybrid:

• Private cloud networks are owned and managed by a single organization, and the public cannot access these.
• Public cloud networks are the ones that are owned and operated by a third-party provider and are available to anyone with an internet connection.
• Hybrid cloud networks combine features of both private and public networks for people to offer a balanced combination.

Hardware

Hardware is a physical machine or a tool that can be kept anywhere and is used to connect computing machines to a cloud. Hardware components comprise servers, power supplies, memory and storage, processing units, and more — all of which play a significant role in delivering services, information, and security to businesses and individuals.

Benefits of Cloud Infrastructure

Here are the main benefits of using a cloud infrastructure:

Flexibility

Cloud infrastructure helps you with easy and quick access to resources that you can use to self-manage and better align the infrastructure for your business needs.

Reliability

Cloud vendors build and maintain extensive infrastructure, providing various tedium options using availability zones to deliver dependability at scale. Each vendor offers distinct service level agreements (SLAs) that guarantee a certain level of availability.

Cost

cloud infrastructure can eradicate upfront capital costs spent on on-premises infrastructure, using a consumption-based model to deliver infrastructure readily. Cloud vendors use a pay-per-usage model to bill users for the infrastructure they use hourly, weekly, or monthly.

Security

cloud vendors invest in and enhance their infrastructure security and provide customers with attributes to set up their security controls. Cloud infrastructure allows you to access high-end security features that are inaccessible or too pricey.

Cloud Computing Infrastructure Best Practices

Migrating to and adopting cloud infrastructure could be quite challenging, given the security considerations and the intricacies. Here are a few best practices you could stick to while starting your journey with cloud computing infrastructure:

1. Switching to cloud computing infrastructure is a strategic change in your business and should be approached with the exact focus on policies as any other change. It ensures a seamless transition and brings the entire organization on board with the switch.
2. You must thoroughly research the diverse cloud solutions and options and choose the cloud infrastructure that best supports your requirements — both in the delivery models illustrated above and the potential of different cloud networks for your distinct business operations.
3. Analyze how to use modern technology to your benefit. Cloud servers support the use of these tools, and it is worth probing whether they can help with automating your services or supporting a global expansion plan.
4. Carry out tier optimization to make the most typically accessed data easier to find on a higher level as compared to the one that is rarely searched for and opened. This simple trick can streamline internal and external access within the network and works similarly to a multi-tiered file manager.
5. Governance is essential to ensure that your data is always secure and up to date. It is worth having a contingency plan in case of any unforeseeable disaster. It is not unlikely that things can go wrong where technology is involved, so putting in place a risk mitigation plan is a reasonable way of training for the worst and guaranteeing that should it happen, your team knows what to do.

Wrapping it up

Up until now, IT equipment and data center systems worked on the circled wagon approach. Everything was behind a firewall and facing inward. The only users were inside the company and the firewall, as were the apps used by them.

The cloud – and to some extent mobile – forces a pause in that circle. Now, businesses need to face outward to cloud companies. Businesses must create a secure data flow in their firewall to connect securely to the public cloud and keep invaders out while at the same time maintaining optimum levels of performance. Now, here is the thing. There is a common delusion among organizations that migrating workloads to cloud infrastructure will automatically result in cost savings. In reality, that is not always the truth.

Reducing cloud costs and maximizing cloud infrastructure ROI should always be a conscious decision. Along with this, cloud security is a growing concern for organizations and businesses relying on cloud infrastructure to deliver the underlying resources that support fundamental business services.

Whether you are contemplating signing up for cloud services or working in the cloud industry, a good understanding of the cloud infrastructure opens a range of possibilities for you. As a business leader, you can optimize and automate the primary processes, saving time and improving productivity.
