Yes securities like a traditional broking house was always on an on-premise model with complete infrastructure in a collocated managed datacenter.“Since the capex was already incurred there was no reason to move to the public cloud,” said Aneesha Pant, CTO, Yes Securities.
As the company started its journey on building new age business solutions, a small development team was set up and a complete DevOps environment was required. In order to do that, Yes Securities felt the need to explore the public cloud.
Both AWS and Azure platforms were evaluated and finally AWS was chosen. Development servers, VDI, GitLab were established and the native CI/CD capabilities were used.
Pant believes that compute is still possible to manage, however, the storage is ever growing in today’s world and has become difficult to predict.
As increasing infra at the company’s own data center takes a lot of planning and time, Yes Securities’ current focus is to explore public cloud offering rather than expanding its own datacenter.
For the investment banking firm, moving the UAT loads to the cloud is the next target for which sizing and evaluation is currently ongoing.
While most of the public clouds offer Multiple high availability zones that is not enough by itself, Pant believes. For enterprises, it is critical to plan a proper backup and recovery plan for production environments.
“We are architecting it in a manner we can utilize the best of both worlds. A hybrid architecture where we leverage the advantages of cloud at the same time utilize the infra /tools already bought,” Pant said about the broking firm’s strategy.
Talking about scaling IT infra as per demand, Pant said, the test servers have the maximum variations in load when testing is done. “They are used to the capacity and there are long stretches of disuse. Having it on the public cloud helps reduce costs by optimizing the usage and not blocking the infrastructure. This leads to not only cost reduction but also gives scalability when needed.”
Security has always been among the biggest challenges for organisations when it comes to handling multiple clouds. According to Pant, Yes Securities has addressed this in multiple ways and a few options like a landing zone and creating segregated environments, transit gateways, VPN tunnels are also being evaluated with the environment.
