VPC Oversight
an analysis of the edge VPC's IaC characteristics utilising IBM Cloud's deployable architecture. Because cloud infrastructure is always evolving, many organisations are now compelled to establish a safe and adaptable virtual private cloud (VPC) environment within a single region. The VPC landing zone deployable architectures satisfy this need by offering a set of basic templates that can be readily modified to suit your particular requirements.
The VPC Landing Zone deployable design lets you define your infrastructure in code and automate its deployment by utilising Infrastructure as Code (IaC) ideas. By using this technique, you can easily update and manage your edge VPC configuration and promote consistency throughout deployments.
One of the key benefits of the VPC Landing Zone is its versatility. You can easily modify the initial templates to fit the specific needs of your company. This may need adding extra resources, such as load balancers or block volumes, as well as adjusting network and security configurations. The following patterns are beginning templates that you can use right away.
Configuring an Edge VPC
- Pattern of VPCs in the landing zone: Installs a minimal version of the IBM Cloud VPC architecture without any computing resources installed, like VSIs or Red Hat OpenShift clusters.
- Virtual server instances (VSI) with QuickStart pattern: An edge VPC with one VSI and a jump server VSI are installed together in the management VPC.
- QuickStart ROKS pattern: This pattern deploys a single ROKS cluster with two worker nodes in a workload virtual private cloud (VPC).
- Virtual server (VSI) pattern: Using the VSI subnet layer, the same virtual servers are deployed in each VPC.
- Red Hat Open Shift pattern: According to the Red Hat Open Shift Kubernetes (ROKS) architecture, a single cluster is deployed at each VPC's VSI subnet layer.
VPC Patterns that follow suggested guidelines
- Create a resource group to plan and manage cloud services and VPCs.
- Set up instances of Cloud Object Storage to store flow logs and Activity Tracker data.
- This enables the long-term archiving and analysis of flow logs and Activity Tracker data.
- When using Key Protect or Hyper Protect Crypto Services, keep your encryption keys safe. This provides a convenient and secure area for the management of encryption keys.
- Create a workload virtual private cloud (VPC) to run applications and services, and a management VPC to keep an eye on and manage network traffic.
- Connect the management and workload VPCs using a transport gateway.
- Install flow log collectors in each virtual private cloud (VPC) to collect and analyse network traffic data. This provides information about the performance and patterns of network traffic as well as visibility.
- Configure the necessary networking rules to provide connectivity for VPC, instances, and services.
- Among these are security groups, network ACLs, and route tables.
- Set up the VPEs for Cloud Object Storage in each VPC.
- This makes it possible for each VPC to have secure, private access to Cloud Object Storage.
- Turn on the management VPN gateway for the VPC.
- This makes it possible for encrypted and safe communication between the on-premises networks and the management VPC.
Landing zone patterns
Let's explore the Landing Zone patterns in order to have a comprehensive understanding of their basic concepts and applications.
Initially, the VPC Pattern
The VPC Pattern design stands out as a modular solution that offers a solid foundation for developing or deploying compute resources as needed. With this design, you may expand your cloud environment's computational capacity by adding virtual private islands (VSIs) or Red Hat OpenShift clusters. This approach ensures that your cloud infrastructure is secure and adaptable enough to meet the evolving needs of your projects, while also simplifying the deployment process.
QuickStart VSI pattern with edge VPC
The Quickstart VSI pattern pattern involves deploying an edge VPC with a load balancer inside and one VSI in each of the three subnets. Additionally, it has a jump server VSI in the management VPC that makes a public floating IP address available. It is important to keep in mind that this architecture does not guarantee high availability or validation within the IBM Cloud for Financial Services framework, even if it can help you get started quickly.
ROKS pattern QuickStart
The Quickstart ROKS pattern pattern consists of a security group, an allow-all ACL, and a management VPC with a single subnet. Two subnets situated in two different availability zones, an allow-all ACL, and a security group are all present in the Workload VPC. The management and workload VPCs are connected by a Transit Gateway.
A single ROKS cluster with two worker nodes and an enabled public endpoint is also present in the workload VPC. To enhance security, the cluster keys are encrypted through the use of Key Protect, and setting up a Cloud Object Storage instance is a must for the ROKS cluster.
Virtual server pattern
The VSI pattern design in question makes it easier to establish a VSI on a VPC landing zone within the IBM Cloud environment. The VPC landing zone is a crucial component of IBM Cloud's secure infrastructure services, providing a secure platform for workload deployment and management. The VSI on VPC landing zone architecture was specifically designed to provide a secure infrastructure using virtual servers to execute applications on a VPC network.
Red Hat OpenShift Pattern
- The Red Hat OpenShift Container Platform may be set up and implemented more easily in a single region inside a VPC landing zone on IBM Cloud thanks to the architecture of the ROKS pattern.
- This enables the administration and operation of container apps in a secure, segregated environment that provides the resources and services needed to keep them effective.
- For applications deployed in this environment, a single-region architecture reduces latency and improves performance because all components are situated inside the same geographic area.
- It also facilitates the setup and use of the OpenShift platform.
- By setting up and managing their container infrastructure in IBM Cloud's VPC landing zone, organisations can quickly and efficiently deploy and manage their container apps in a secure and scalable environment.
