Azure Bastion vs ExpressRoute Which Azure networking solution is the best

Azure Bastion vs ExpressRoute: In the ever-evolving landscape of cloud networking, organizations must choose the right solutions to ensure secure and efficient connectivity to their Azure resources. Two prominent options offered by Microsoft Azure are Azure Bastion and ExpressRoute. In this comprehensive guide, we’ll delve into the features, benefits, and use cases of each, along with providing a detailed comparison to help you make an informed decision for your networking needs.

Understanding Azure Bastion and ExpressRoute

Azure Bastion: Azure Bastion is a fully managed Platform-as-a-Service (PaaS) solution that provides secure and seamless RDP and SSH connectivity to Azure VMs directly from the Azure portal. It acts as a bastion host, eliminating the need to expose VMs to the public internet and reducing the attack surface.

ExpressRoute: Azure ExpressRoute is a dedicated private connection to Azure that bypasses the public internet, offering higher security, reliability, and predictable performance. It enables organizations to establish private connections between their on-premises infrastructure and Azure data centers, ensuring a seamless hybrid cloud experience.
