Cloud Foundry replacement is a complex process, but having a solid strategy in place can make all the difference.

First, identify the reasons for replacing Cloud Foundry. According to our analysis, the top reasons for replacement include scalability issues, high costs, and limited customization options.

Next, assess your current infrastructure and applications to determine the best replacement approach. This includes evaluating the compatibility of your existing applications with the new platform.

Consider replatforming, which involves migrating your applications to a new Cloud Foundry-based platform, such as Pivotal Cloud Foundry. This approach can provide a seamless transition and minimize downtime.

Migration Process and Tools

The migration process using a cloud migration starter kit can be a complex and time-consuming task, but it doesn't have to be. The process typically takes anywhere from 1 to 3 months, depending on the toolset and development team's capacity. This is because it requires creating and implementing a platform blueprint with technology choices for each box, which can be a repetitive process.

The starter kit helps to accelerate the time-to-market with little to no disruption to the wider business ecosystem. It does this by providing a reusable reference implementation for the platform, which includes all the "plumbing" needed to get started.

The starter kit can be used to migrate from Pivotal Cloud Foundry (PCF) to AWS EKS, for example. This is a common use case, as many customers want to future-proof themselves and cut down on licensing costs. The starter kit provides a pre-configured solution that can be customized to meet the specific needs of the customer.

The migration process using the starter kit involves several steps. Here's a high-level overview of what you can expect:

  • Analyze the Real PCF organization using conversion tools to detect all microservices and PCF-native services.
  • Enrich the configuration files with external details like role mappings and Git repositories.
  • Generate Kubernetes manifests for the applications detected.
  • Deploy the infrastructure, mapping CF-native services to AWS-based counterparts.
  • Replace secrets with new AWS-based service credentials using AWS Secrets Manager.
  • Use the ExternalSecrets add-on to create Kubernetes secrets.
  • Deploy the applications to EKS.

Note that a lot of action happens behind the scenes, including the implementation of CI/CD pipelines.

Cloud Platforms for Replacement

Cloud platforms are not one-size-fits-all solutions, with multiple options available for different workloads and integrations. Kubernetes is a popular choice for running containerized applications in the cloud, but it's not a straightforward solution.

There is no single "holy grail" technology for microservices platforms, and different solutions can be chosen based on workload specifics and team preference. The general architecture of a microservices platform can be implemented on top of any modern cloud or on-premise system.

Red Hat OpenShift

Red Hat OpenShift is a Cloud Computing Platform as a Service (PaaS) offering from Red Hat. It's an application platform in the cloud where developers and teams can build, test, deploy, and run their applications.

One notable drawback of Red Hat OpenShift is that decisions are made for you, limiting your options. This might not be ideal for those who value flexibility.

Red Hat OpenShift comes with a license cost, which could be a factor in your decision-making process. Consider your budget before committing to this platform.

Unfortunately, Red Hat OpenShift can sometimes fall behind the upstreams, which might impact its performance and security. This is something to keep in mind when evaluating its reliability.

Docker

Docker is a popular containerization platform that allows developers to package their applications and dependencies into a single container, making it easy to deploy and manage applications across different environments.

Docker containers are lightweight and portable, requiring minimal resources and allowing for faster deployment and scaling of applications. They also provide a consistent and reliable way to run applications, regardless of the underlying infrastructure.

Docker uses a layer-based approach to package applications, allowing for efficient reuse of layers and reducing the size of the container image. This approach also enables fast and efficient deployment of applications.

Docker has become a widely adopted technology in the cloud, with many cloud platforms supporting Docker containers natively.

Kubernetes

Kubernetes is a leading container management solution with a simple and powerful architecture. It's an open source tool backed by Google.

Kubernetes is known for its scalability, allowing you to scale services with ease. Replication controller is one of its key features, ensuring high reliability and availability.

Here are some of the benefits of using Kubernetes:

  • It supports autoscaling, making it easy to adjust resources as needed.
  • Kubernetes promotes modern infrastructure practices.
  • It's a self-healing environment with rich metadata.
  • It's cloud-agnostic, allowing you to run it on various cloud platforms.
  • Kubernetes is backed by Red Hat and runs on Azure.

However, Kubernetes also has its downsides. It has a steep learning curve, which can be a barrier for new users. Additionally, it has a high resource requirement for on-prem clusters, making it unsuitable for simple systems.

Heroku Platform

Heroku Platform is a platform-as-a-service (PaaS) offering that's now part of Salesforce. It's designed for deploying modern apps, with integrated data services and an ecosystem for developers to work with.

Heroku takes an app-centric approach to software delivery, integrating with developer tools and workflows. At its core are three main tools: Heroku Developer Experience (DX), Heroku Operational Experience (OpEx), and Heroku Runtime.

Developers can deploy directly from tools like Git, GitHub, or other platforms, thanks to Heroku's DX tool. This makes it easy to create, replicate, and manage development environments.

Here are some key benefits of using Heroku:

  • Easy deployment
  • Free for side projects
  • Huge time-saver
  • Simple scaling
  • Low devops skills required
  • Easy setup
  • Add-ons for almost everything
  • Beginner-friendly
  • Better for startups
  • Low learning curve

However, some users have noted that Heroku can be super expensive, especially for large-scale applications. Additionally, the platform has limited flexibility and no usable MySQL option on its free tier.

Build a Strong Foundation with a Microservices Platform

Building a strong foundation with a microservices platform is key to a successful cloud migration. This involves choosing the right technology for your workload specifics and required external integrations.

A microservices platform is not a one-size-fits-all solution, with multiple options available in the market. You can choose from various solutions based on your workload specifics, adoption complexity, or team preference.

The general architecture of a microservices platform remains the same, regardless of the technology chosen. This architecture can be implemented on top of any modern cloud or on-premise system, making it portable.

One popular platform for building a microservices platform is Kubernetes, which is available as a managed service offering from all major cloud providers. However, simply putting a container in Kubernetes is not enough; you need to address dozens of questions and carefully choose technologies to achieve your goal.

Here are some key benefits of using a microservices platform:

  • Save time and money by cutting infrastructure provisioning time by at least 60%
  • Co-innovate in a fully pre-integrated environment
  • Migrate without changing the existing code
  • Educate your team about migration best practices

IBM Managed Istio

IBM Managed Istio is a game-changer for cluster management. It provides additional control over clusters and the microservices they comprise.

The Managed Istio installation add-on is designed to make life easier for developers and administrators alike. It offers automatic updates and lifecycle management of control plane components.

This means you can focus on writing code and building applications, while IBM takes care of the rest. No more worrying about outdated software or manual updates.
