Skills

Multi-Tenanted Platform

I manage on daily basis multiple multi-tenanted platforms at high traffic:
- over 3-10 millions concurrents users
- over 500 applications deployed through a continuous delivery pipeline
- over 1000 developers using the platform
- infrastructure tested to handle 1 million TPS

Technology Agnostic

I use various langages, because I think it’s important to choose the right technology to solve a given problem:
- Kubernetes, Docker as Early adopter
- Golang, Nodejs, Java, Python
- ReactJs, VueJs, Ionic, Cypress
- Gatling, Prometheus, Akamai, Cloudflare
- Redis, Cassandra, Postgres, Kafka

Architect & Design

I design and implement scalable solution related to:
- microservices (caching, circuit breaker, fallback)
- logging
- monitoring
- load testing
- networking
- load balancing
to scale depending on the traffic.

Observability & Alerting

Monitoring and Alerting are essential to allow fast diagnostic and prevent issue:
- define your SLO and monitor your application
- create KPIs
- follow the golden signals
- alert early to prevent problem and outage

Scalibility & Reliability

Integrate chaos testing, rolling deployment as part of your load test. It’s very important to anticipate the growth and avoid any problem.

Extensive testing

Every application should be deployed through a continuous delivery pipeline including tests:
- Unit
- Integration
- Functional
- NFT
- Load
- Chaos
- Gating via alerting before promoting

Kubecon EBPF & Cilium at Sky Presentation In addition to the “EBPF Summit 2021 - Presentation” and my previous post about Cilium & EBPF. I got the chance to present “eBPF & Cillium at Sky” at Kubecon 2021, we are explaining how we have been embracing EBPF and Cilium at Sky and how our automated tests help us to mitigate the risk of introducing new technology without affecting tenants of the platform and ultimately our customers.

Kubernetes Cross Cluster Communication

Kubernetes Cross Cluster Communication Depending on your requirements and needs, you might not need cross cluster communication at the pod level. In most cases, stateless components are running within your cluster and talking to some stateful components like databases which are running outside of the cluster. This is a common approach right now because it is still very difficult to run stateful components on a kubernetes cluster even if some solutions exist like statefulsets which add ordering and stable dns for your pods.

Kubernetes Network Policies - Cilium & EBPF

Secure your network with network policies Kubernetes comes with a flat network by default where every pod can talk to each other. Kubernetes Network Policy is a concept which allows you to segregate the network within your cluster. Multiple CNI are available to implement network policies. Cilium and Calico are the main CNI available to secure your network. Initially Calico was relying on iptables rules to block/allow ingress/egress traffic related to your pod.
