<h3><strong>2.Why Tanzu Service Mesh?</strong></h3>
<p>As organizations increasingly adopt microservices architectures, the complexity of managing service-to-service communication grows. Traditional networking solutions often fall short in providing the necessary security, observability, and reliability required for modern applications. Tanzu Service Mesh, deployed on a cloud platform, addresses these challenges by providing:</p>
<h4><strong>Secure Communication:</strong></h4>
<p>TSM uses mutual TLS (mTLS) to secure all inter-service traffic, ensuring that only authorized services can communicate with each other.</p>
<h4><strong>Traffic Management:</strong></h4>
<p>It allows for sophisticated traffic control capabilities, including load balancing, traffic splitting, and canary deployments.</p>
<h4><strong>Observability:</strong></h4>
<p>TSM provides deep insights into service interactions, enabling teams to monitor performance and troubleshoot issues effectively.</p>
<h4><strong>Policy Enforcement:</strong></h4>
<p>Organizations can define and enforce security policies across their services, ensuring compliance and reducing risk.</p>
<h3> </h3>
<h3><strong>3.Features and Capabilities of Tanzu Service Mesh</strong></h3>

<h4><strong>Out-of-the-Box Multi-Cloud Support:</strong></h4>
<p>TSM enables seamless integration across different cloud environments, allowing organizations to deploy applications without worrying about underlying infrastructure differences.</p>
<h4><strong>Automatic High Availability:</strong></h4>
<p>The service mesh automatically manages service instances across multiple clouds, providing load balancing and failover capabilities.</p>
<h4><strong>Service-Level Objectives (SLOs):</strong></h4>
<p>TSM allows teams to define and track SLOs, enabling proactive management of application performance.</p>
<h4><strong>End-to-End mTLS:</strong></h4>
<p>With zero operator effort, TSM secures all inter-service communication using mTLS, ensuring that both client and server identities are verified.</p>
<h4><strong>Security Policies and Auditing:</strong></h4>
<p>Organizations can create detailed security policies that dictate which services can communicate, enhancing overall security posture.</p>
<h4><strong>Full Workload Visualization:</strong></h4>
<p>TSM provides real-time visualizations of all services within the mesh, complete with metrics for performance monitoring.</p>
<h4><strong>Traffic Control Features:</strong></h4>
<p>TSM supports advanced traffic management features such as traffic shaping, canary deployments, and A/B testing.</p>
<p>&nbsp;</p>
<h3><strong>4.Getting Started with Tanzu Service Mesh</strong></h3>
<p>To deploy applications securely with Tanzu Service Mesh on a cloud platform, follow these steps:</p>
<h4><strong>Onboarding Kubernetes Clusters:</strong></h4>
<p>Start by integrating your Kubernetes clusters with TSM. This involves installing the TSM components in your clusters and configuring them to communicate with the TSM control plane.</p>
<h4><strong>Creating a Global Namespace:</strong></h4>
<p>Set up a Global Namespace in TSM, which acts as a logical grouping of services across different clusters. This simplifies service discovery and management.</p>
<h4><strong>Installing Services:</strong></h4>
<p>Deploy your applications as services within the Global Namespace. Ensure that each service is configured to use mTLS for secure communication.</p>
<h4><strong>Accessing Applications:</strong></h4>
<p>Use the TSM control plane to manage access to your applications, ensuring that only authorized users and services can interact with them.</p>
<h4><strong>Generating Application Traffic:</strong></h4>
<p>Once your services are deployed, generate traffic to test the inter-service communication and validate the security configurations.</p>
