Say hello to simplicity and faster time to market

T-Systems fully managed ROSA service - RedHat OpenShift on AWS - removes infrastructure management headaches and eliminates the need for complex, multi-year contracts with an elegant single provider experience. Enterprises can realize a host of economic, compliance, and efficiency benefits. Learn what ROSA is and how it works, the focus of the service, and the roles and responsibilities of the client organization and the key players.     

What is RedHat OpenShift on AWS?

Three people evaluating graphics.

OpenShift is a Kubernetes container platform, offering a trusted environment for enterprise workloads across hybrid cloud environments and providers. Using Red Hat OpenShift, the Red Hat OpenShift Service on AWS (ROSA) manages containerized services and workloads across multiple hosts. The service includes management tools for deploying, monitoring, and scaling containerized apps in an automated way. 

RedHat OpenShift on AWS in brief  

The Red Hat OpenShift Service on AWS (ROSA) is a turnkey application and enterprise Kubernetes platform. The fully managed service enables organizations to create Kubernetes clusters quickly and easily via the AWS console with seamless access to all AWS services using familiar APIs and tools from Red Hat OpenShift.

Our Cloud Native Managed ROSA Service

As an AWS certified Managed Service Provider, we support our clients with an AWS native managed Red Hat OpenShift on AWS (ROSA) as a managed OpenShift solution.

Managed ROSA as a service allows you to focus on delivering value to your end-users. AWS Site Reliability Engineers (SREs) and Red Hat experts take care of the underlying platform to save you from the complexity and hassle of infrastructure management. Moreover, given the seamless integration of ROSA with a wide range of AWS analytics, networking, compute, mobile, machine learning, and other AWS services, ROSA lends itself to excellent customer experiences by speeding up the delivery of services.   

Our ROSA service – like cargo on a ship

One container doesn’t make up the application. So, we have ten plus containers making up one application. If one function doesn’t run, the application breaks, so it’s vital that we can bundle the containers and make sure that they will run together. Here’s where containers come in. In containers, we will make a deployment (set of containers) as a shipping document on a boat. Once onboard, it will stay or will be replaced by another (the same) container. It’s also possible to add more containers for failover and capacity.

ROSA uses CRI-O as the container runtime to deploy containers to your cluster.

Our managed ROSA service functions on two levels:

  • Advanced (focusing on AWS infrastructure)
  • Value Added Services (SRE, Application Operations

The focus of our advanced ROSA service 

The advanced element of our managed ROSA service primarily focuses on the following aspects:

• 24/7 operation support, including support solving everyday issues, like networking and low performance

• Proactive monitoring for security, networking, or performance issues using AWS best practices

• Seamless integration into AWS native services and our AWS managed cloud service ecosystem (e.g., monitoring, audit logs, billing, and provisioning)

Our consultancy power allows us to provide customers with value-added services. Key areas are security, networking, performance, and support of customer-specific requirements.

What are the benefits of ROSA?   

Our service brings economic, compliance, and efficiency advantages, including:

  • Cost - ROSA brings elasticity and pay-as-you-go pricing to Red Hat OpenShift through a new Red Hat subscription. It eliminates the need for complex, multi-year contracts and enables companies to tailor Red Hat OpenShift on AWS to their business needs.
  • Simplicity - With ROSA, companies can now access a Red Hat OpenShift subscription with billing and support directly from AWS. This gives the simplicity of a single provider experience and frees organizations from the procurement and operational complexities associated with having two separate providers.
  • Compliance - ROSA meets important compliance guidelines, including SOC 2ISO 27001, and PCI security standards.
  • Quicker Time to Market – As an OpenShift managed by Red Hat, ROSA enables customers to easily change or add a specific application function because they don‘t have to consider other functions. This means effective DEVOPS and faster time-to-market. 

ROSA – the roles and responsibilities

While Red Hat and Amazon Web Services (AWS) manage the Red Hat OpenShift Service on AWS, T-Systems and the customer share certain responsibilities. The ROSA services are accessed remotely, created in customer-owned AWS accounts, hosted on public cloud resources, and have an underlying platform and data security that Red Hat owns. The customer, Red Hat, and AWS share responsibility for the monitoring and maintenance of a Red Hat OpenShift Service on the AWS cluster.

Wrapping up

Adopting cloud-native applications is the key to business agility and success. And given that cloud-native applications like ROSA use reusable and discrete components, it accelerates the development and deployment process and speeds time-to-market. Moreover, as our ROSA service is based on a microservices architecture, the focus is on building new applications while also supporting the modernization of existing ones. All processes reflect best practices and are fully optimized for cloud computing and agility.
