A funnel icon represents the limitations of VMs. They are not as scalable or agile as containerized applications. Scaling a VM requires provisioning a whole new server, while scaling a containerized application simply involves spinning up more containers.

How we reduced Kafka message latency by 90% and increased throughput 4x for a $300M SaaS platform.

We work with a large-scale enterprise in the digital communications governance domain as a SaaS provider (~$300M ARR). They use Apache Kafka to power their event-driven architecture. One of their products was being rolled out to many new tenants (increasing the traffic by 2x). During this roll-out phase, their Kafka-based async data pipeline experienced significant performance degradation. This caused cascading ripple effects throughout the other system, making the product unusable. We investigated and fixed this problem and eventually enabled the product to support 5 times the anticipated scale.

Journey of moving VM-based workloads to Kubernetes

Flip is a fintech company in Indonesia. We migrated their stateless services running on 25+ VMs in the Alibaba cloud to their managed Kubernetes offering (ACK). These application services served Flip's B2B and B2C traffic which often peaked at 25,000 requests/second. Problem Statement. Implement autoscaling of the infrastructure to handle peak traffic. Move to a Cloud-Native architecture to use modern tooling. Solve the problems related to configuration management and operational toil.

Migrating from Heroku PaaS to AWS

When ADPList approached us, they had an immediate problem at hand. The latency for the business critical APIs was high and caused poor user experience. Before anything else, we started focusing on solving that problem. The entire stack for ADPList was running on Heroku. To improve performance, the ADPList team already implemented vertical infrastructure scaling. However, this resulted in a massive increase in costs. Apart from the costs, we realized that Heroku isn’t particularly suited well for microservices deployments at ADPList due to:
