Auto Trader (UK), the largest digital automotive marketplace in the United Kingdom, was facing challenges with its existing infrastructure. The company's infrastructure was previously deployed from its own data centers via a private cloud. The company wanted to improve its security and encryption, and create a more agile architecture to enable faster innovation. Auto Trader (UK) wanted to upgrade its security layers and implement mutual Transport Layer Security (mTLS) authentication between its apps. However, retrofitting these changes to its previous infrastructure would have been difficult due to the complexity of modifying hundreds of applications and building additional elements. The company also wanted to optimize its CPU allocation, which was previously uniform across all instances due to the inability to accurately measure the impact of changes.
To overcome these challenges, Auto Trader (UK) decided to migrate from a virtual machine-based infrastructure to a containerized one on a public cloud. The company moved its backend applications to Kubernetes Engine (GKE) and implemented Istio, an open-source, transparent service mesh. This move was aimed at achieving their security goals and making system improvements. Istio provided the company with increased visibility over applications in terms of response times and other important service metrics. This increased visibility enabled Auto Trader (UK) to optimize its CPU allocation by adjusting CPU and RAM in GKE and observing the impact across all performance metrics. The company also implemented automation to reduce operational overheads, using Cloud Load Balancing to spread instances over three zones and serve their domain names using Cloud DNS. Auto Trader (UK) also started using Network Intelligence Center for network monitoring and gaining visibility into the network.
