If you are part of a CloudOps team or a cloud network engineer, you probably receive daily tickets from developers that look something like this: My instance suddenly cannot “ssh” into this server. Is something wrong with the network? Please help resolve. I get my instance up and running, but it cannot access the Internet. Is something wrong with the network? Please help resolve. No one can access my application. Is something wrong with the network? Please help resolve. …. You get the idea. For any connectivity problem, the network is always the first to be blamed. To resolve the…

The Aviatrix AWS Global Transit Solution has been published on the AWS Answer page as a partner solution. Since then we are often asked by customers why they should consider the Aviatrix solution, and for that matter, why they should consider Aviatrix over all other virtual appliance-based solutions. This article tries to answer some of the questions. 1. Who should use the Aviatrix solution? If you are not a CCIE with domain expertise in VRF, BGP and IPSEC, you should not consider the CSR-based solution.

We recently did a survey on popular DevOps tools and discovered some normal stuff — most of them are client server based; also learned something new — most of them are not encrypted. Tools like Chef, Puppet, Jenkins, etc, where data packets between client and server travel in clear text. Typically in a cloud deployment, there is a shared service VPC or management VPC where DevOps tools are deployed. Application instances are hosted in spoke VPCs. Most of the application images have agents installed, enabling them to be managed by servers residing in the management VPC. DevOps tools, either for build, configuration or test,…

Cloud Migration is Complex with Uncertainty If you take a look at AWS guide to enterprise on how to migrate on-prem VMs to cloud since 2014, you’ll find the workflow is getting more complex each year and the task more daunting. The Current Migration Process Before getting started, you need first to run some inventory tool to scan what VMs and their operating systems are in your organization, then use dependency tool to map dependencies between VMs or Apps on these VMs. The dependency map quickly turns into a spider web as apps need database and need other apps to…

As cloud technologies evolve, so do the requirements for cloud networking. Now, it’s time for an entirely new architecture for networking in the public cloud. The Shared Service Architecture for DevOps Consider the evolution of Amazon Web Services (AWS). In 2006, AWS started with EC2 Classic where there was not much networking to do: an EC2 instance either has a public IP address or a 10.0.0.0/8 network. Later in 2009, AWS introduced Virtual Private Cloud (VPC). Nowadays you cannot launch an EC2 instance without specifying which region, VPC, and subnet the EC2 instance will be deployed on. You can think…
