Your cloud migration strategy can make or break your cloud transformation. At least 50% of cloud migration projects end up exceeding their budgets and worse, up to 70% fail miserably, reports said. Choosing the right strategy that aligns with your business needs and goals can be a tricky task. This blog explores the various factors an organization should consider and different strategies so the enterprise can ensure a successful transition to cloud.
Why migrate to cloud?
Cloud migration refers to transferring a company’s data, applications, and digital assets from on-premises infrastructure to cloud-based servers. Cloud migration services impart the following benefits for businesses:
- Migration allows companies to reduce their reliance on expensive hardware and IT personnel, thus reducing costs.
- Cloud services are highly scalable and can easily accommodate changes in demand, allowing businesses to quickly and efficiently scale up or down as needed.
- Cloud services offer accessibility and collaboration opportunities, allowing employees to access information from anywhere with an internet connection.
- Moving forward from migration, cloud managed services help set up your data security, with greater protection against data loss and cyberattacks.
Cloud migration offers a range of benefits for businesses, making it attractive for organizations looking to optimize their operations. The right migration strategy helps organizations avail these benefits faster and in a more efficient manner.
Identify Your Business’s Needs
To make a well-informed decision about your cloud migration strategy, it is vital to first identify your business’s needs.
Assess Your Current Infrastructure
Assessing your current infrastructure involves understanding your IT environment, including your hardware, software, and networking infrastructure. You must evaluate their performance and identify any gaps that must be addressed.
Identifying Your Business’s Goals
Once you have assessed your current infrastructure, identify your business goals. Understand what your organization wants to achieve through cloud migration. Do you want to improve your business agility? Are you looking to reduce your IT costs? Do you want to enhance your data security? Your business goals will determine which cloud migration strategy is best suited for your organization.
You can choose from a few common cloud migration strategies based on your infrastructure assessment and business goals.
Which cloud migration strategy should you choose?
Rehosting, also known as lift-and-shift, is the most straightforward cloud migration strategy. In rehosting, applications are moved from on-premises to the cloud without modifying the underlying code or architecture. This approach involves moving the entire application stack to the cloud, including the operating system, application server, and data. The goal is to make the application operational in the cloud with minimal changes.
Rehosting is a fast and straightforward way to migrate applications to the cloud. It requires minimal re-architecture and can be accomplished quickly. However, it does not take advantage of the cloud’s native features, which can limit the application’s scalability, performance, and cost efficiency.
Refactoring, or re-coding, involves changing the application’s code to optimize it for the cloud. This approach involves breaking down monolithic applications into smaller, more manageable components that can use cloud-native services, such as storage, computing, and messaging.
Refactoring requires significant code changes and may require a redesign of the application architecture. It takes more time and effort than rehosting, but it can provide substantial benefits, such as improved scalability, performance, and cost efficiency.
Re-platforming, or lift-and-optimize, involves moving an application to a cloud platform that provides similar services to the on-premises environment. This approach involves minimal changes to the application’s code but takes advantage of the cloud platform’s native features, such as scaling, load balancing, and auto-scaling.
Re-platforming is a faster and less risky approach than refactoring, but it may not provide all the benefits of cloud-native services. It can be a good option for applications independent of specific infrastructure or architecture.
Re-architecting, also known as rebuilding, involves redesigning an application’s architecture to take full advantage of cloud-native services. This approach involves breaking down monolithic applications into microservices and using cloud-native services, such as containers, serverless computing, and NoSQL databases.
Re-architecting requires significant changes to the application’s architecture and code. It is the most time-consuming and expensive cloud migration strategy, but it can provide significant benefits, such as improved scalability, flexibility, and cost efficiency.
The right cloud migration strategy depends on the organization’s goals, timelines, and budget. Rehosting is the fastest and least risky approach, while re-architecting is the most complex but provides the most significant benefits. Refactoring and re-platforming fall in between and provide a balance between speed, risk, and benefits.
How to choose a strategy that works for you
Cloud transformation services provide business with access to the latest tools and services that help them better innovate and thrive on the cloud. This process begins wih choosing a cloud migration strategy that will help an organization achieve its goals. Consider the following aspects before choosing your strategy:
Consider your resources and budget
Cloud migration can be expensive, and it is essential to consider your organization’s resources and budget before embarking on a migration project. Cloud service providers offer a variety of pricing models — a pay-as-you-go model may be more suitable for organizations with fluctuating workloads, while a reserved instance model may be more cost-effective for organizations with predictable workloads.
Analyze your current and future needs
It is essential to analyze your organization’s current and future needs. Consider the types of applications and data to be migrated and how they will be used. For example, if your organization plans to use cloud-based analytics tools, you may choose a migration strategy that supports big data processing.
Evaluate the risk of each strategy
Consider data security, compliance, and data residency requirements. For example, if your organization deals with sensitive data such as personal health information, choosing a migration strategy that ensures data security and compliance is a necessity.
Determine your migration approach
Every migration approach, including the ones listed in the section above, has pros and cons. For example, a lift-and-shift approach may be suitable for organizations that want to quickly move their applications to the cloud without making significant changes, while a refactoring approach may be more suitable for organizations that want to modernize their applications and take advantage of cloud-native features.
Choose the right cloud provider
There are several cloud providers, such as AWS, Microsoft Azure and Google Cloud Platform. Consider pricing, reliability, scalability, etc., to suit your business needs.
Selecting the right cloud migration strategy requires a thorough understanding of your business needs, available resources, and the different cloud migration strategies. WIth the help of expert cloud migration services, you can craft a well-planned transition and execute it successfully so your organization can benefit from the scalability, cost-efficiency, and agility of cloud compution. However, it’s important to remember that one single approach may not be suitable for every business, and all factors must be explored to choose the one to migrate to the cloud with confidence.
