Cloud computing isn’t just a trend; it’s here to stay. Over 90% of companies worldwide have already moved to the cloud, and those who haven’t are planning to do so soon.¹ From better scalability to increased flexibility, cost savings opportunities, and easier data management, there are many benefits in using the cloud.
If you’re also considering moving your data, applications, and IT resources from on-site infrastructure to the cloud, you’re making a smart business move. To ensure success, you need to have cloud migration strategies.
Transition 101: Preparing Your Business for the Cloud
Here are 6 preparations you’ll need for the cloud migration process to ensure a seamless transition.
1. Assess Existing IT Infrastructure
- Review all the hardware, software, applications, and data you currently use. The goal is to understand what you have, how it works, and how everything fits together. This step is important because it shows what needs to be moved and highlights any potential challenges.
- Identify dependencies between applications and services. Some applications might need specific databases or services to work properly. Mapping these dependencies helps you plan the migration sequence and ensures that important connections aren’t disrupted.
- Analyze how your current systems perform and how much they are used. This helps determine the resources needed in the cloud and spots areas for improvement. For instance, you can combine underused servers in the cloud to save costs.
2. Choose a Suitable Cloud Migration Strategy
With a clear understanding of your existing infrastructure, the next step is to create a cloud plan that matches your business goals. This involves deciding on the cloud model, service model, and provider.
Cloud Model
There are three main types of cloud models: public, private, and hybrid clouds. Each has its advantages and challenges.
- Public clouds are managed by third-party providers and offer scalable resources that you pay for as you use them. They are great for organizations looking for flexibility and cost savings since you don’t need to maintain physical infrastructure. However, they might have security and compliance issues for certain tasks.
- Private clouds are dedicated environments owned and run by the organization. They provide more control and cloud security, making them ideal for sensitive data and applications. But they require a lot of investment in infrastructure and management.
- Hybrid clouds combine both public and private clouds. They offer a balance between flexibility and control, letting organizations use the benefits of both models. Hybrid clouds are especially useful for organizations with a variety of tasks and different security needs.
Service Model
There are three main types of cloud services:
- Infrastructure as a Service (IaaS): This model provides the basic building blocks of computing – virtual machines, storage, and networking. You have complete control and management over your infrastructure.
- Platform as a Service (PaaS): PaaS includes the underlying infrastructure (IaaS) along with development tools, databases, and middleware. This model lets you focus on developing and deploying applications without worrying about the infrastructure.
- Software as a Service (SaaS): SaaS offers ready-to-use applications delivered over the internet. It’s the most user-friendly option and requires minimal management from your IT team.
Your choice of cloud model depends on factors such as your technical expertise, application needs, and desired level of control.
For example, if your organization has a strong IT team that can manage infrastructure, IaaS might be a good fit. If you have limited IT resources, PaaS or SaaS might be better options. IaaS offers the most control over your environment, while SaaS offers the least. PaaS provides a balance, allowing some customization while managing the infrastructure.
Cloud Service Provider
A cloud provider is a company that offers services, including IaaS, PaaS, and SaaS, over the Internet. There are a lot of cloud providers out there, so when choosing a partner, evaluate the company by considering the following:
- Portfolio: Consider factors like computer power, storage options, security features, and data center locations. Ensure they align with your specific needs.
- Pricing Model: Cloud providers offer various pricing models like pay-as-you-go or reserved instances. Analyze your resource requirements and choose a pricing model that optimizes cost efficiency.
- Security and Compliance: Select a provider with a robust security posture that adheres to relevant industry regulations and compliance standards specific to your data.
- Scalability and Flexibility: The cloud’s advantage is its ability to scale up or down based on demand. Choose a provider that offers the flexibility to accommodate your future growth.
3. Develop a Detailed Migration Plan with Clear Timelines and Milestones
Once you have your team together and listed all your applications and data, it’s time to plan for data migration. This plan will show how you’ll move your applications and data, making sure the process goes smoothly with as little disruption as possible.
For each application you’ve identified in the inventory stage, you can choose the best way to move it:
Lift-and-Shift (Rehosting)
This means moving your application “as-is” to the cloud with very few changes. It’s quick and cost-effective, especially for applications that are already virtualized, and don’t rely much on your on-premises hardware or software. However, it doesn’t fully use the cloud’s ability to scale and optimize performance.
Refactoring
This involves changing the application code to maximize the cloud’s features. You might need to rewrite parts of the code or use cloud-specific services. Refactoring can improve performance and lower costs in the long run, but it requires more development work and might not be possible for all applications.
Re-platforming
This means moving the application to a different platform within the cloud. You might need to do this if the original platform isn’t compatible with the cloud provider or if you want to use a specific cloud-based framework. Re-platforming offers more flexibility than lift-and-shift but still needs some development work to ensure it works with the new platform.
Create a realistic timeline with milestones and deadlines for each phase and decide how much downtime you can handle during the migration. For example, offline batch transfers might be fine for applications that can handle more downtime, while online data replication is better for those needing near-continuous availability.
4. Prioritize Security and Compliance
Prioritizing security and compliance when moving to the cloud is essential to protect sensitive information, comply with regulations, manage risks, build trust, maintain operational integrity, and avoid financial repercussions.
Use strong encryption measures to protect your data during transit and at rest in the cloud environment. Encryption scrambles your data, making it unreadable to anyone without the decryption key
While cloud providers usually have encryption solutions, you can explore other tools for extra security. Make sure your cloud setup follows important regulations and standards like:
- ISO 27001
- FedRAMP (Federal Risk and Authorization Management Program)
- PCI DSS (Payment Card Industry Data Security Standard)
5. Train and Support Your Team
Moving to the cloud involves big changes in technology and how things are done. Your team needs the right training and support to keep everyone on the same page.
Create training programs to teach your team about cloud technologies, best practices, and new processes. This should include technical training for IT staff and basic training for all users.
You can assign a leader to manage the cloud migration project, including planning, execution, and communication. Educate stakeholders about the benefits of moving to the cloud early on, including employees, customers, and partners. Address any concerns and make sure everyone knows how to access the new system so no one is in the dark.
6. Establish a Post-migration Support and Maintenance Plan
Continuously improve the performance of applications and workloads to ensure they run well in the cloud. Set up support systems to help the team during and after the migration by providing access to documentation, resources, and expert support. Encourage teamwork and knowledge sharing to create a strong support network.
Use monitoring tools and set up alerts to manage the cloud environment proactively. This helps find and fix issues before they affect users. Also, regularly check cloud usage and spending to find ways to save money and stay within budget.
