When a user requests for feed then there will be two parallel threads involved in fetching the user feeds to optimize for latency. FUN FACT : In this talk , Dikang Gu, a softwareengineer at Instagram core infra team has mentioned about how they use Cassandra to serve critical usecases, high scalability requirements, and some pain points.
This shift is leading more organizations to hire site reliability engineers to guarantee the reliability and resiliency of their services. How site reliability engineering affects organizations’ bottom line SRE applies the disciplines of softwareengineering to infrastructure management, both on-premises and in the cloud.
In that scenario, the system would need to deal with the data propagation latency directly, for example, by use of timeouts or client-originated update tracking mechanisms. We started seeing increased response latencies and leader servers running at dangerously high utilization.
Snap: a microkernel approach to host networking Marty et al., This paper describes the networking stack, Snap , that has been running in production at Google for the last three years+. You need a lot of softwareengineers and the willingness to rewrite a lot of software to entertain that idea. SOSP’19.
4:45pm-5:45pm NFX 209 File system as a service at Netflix Kishore Kasi , Senior SoftwareEngineer Abstract : As Netflix grows in original content creation, its need for storage is also increasing at a rapid pace. Technology advancements in content creation and consumption have also increased its data footprint. Wednesday?—?December
A few years ago, we decided to address this complexity by spinning up a new initiative, and eventually a new team, to move the complex handling of user and device authentication, and various security protocols and tokens, to the edge of the network, managed by a set of centralized services, and a single team.
The first version of our logger library optimized for storage by deduplicating facts and optimized for network i/o using different compression methods for each fact. Pay the storage, network, and compute cost. While “ keep the design simple ” is a frequently shared learning in softwareengineering, it is not always easy to achieve.
The homepage needs to load in a reasonable amount of time, even in poor network conditions. Server-generated assets, since client-side generation would require the retrieval of many individual images, which would increase latency and time-to-render. Different assets for different device types and screen sizes.

The core algorithms (chain-replication, Paxos-based consensus) aren’t the stars of the show here, instead the paper focuses on how these algorithms are deployed, and the softwareengineering practices behind the creation of a mission-critical production system employing them. A guiding principle. Cells have seven nodes.
degraded hardware, transient networking problem) or, more often, because of some change deployed by Netflix engineers that did not have the intended effect. Two failure modes we focus on are a service becoming slower (increase in response latency) or a service failing outright (returning errors). On error rates.
A site reliability engineer, or SRE, is a role that that encompasses aspects of both softwareengineering and operations/infrastructure. The term site reliability engineering first came into existence at Google in 2003 when a site reliability team was created. At that time, the team was made up of softwareengineers.
Omnipresent connectivity is driving new disruptive business models which are further driving up demands on the networks. Is there an initiative to define a consensus on what “cloud native” means when evaluating virtual network functions? John Abraham] I don’t think so. There is not a consensus yet.

The concept of Zero Trust Networks speaks to this problem. So far, technology has been great at intermediating people for coordination through systems like text messaging, social networks, and collaborative documents. Without moving these experiences into a place that everyone can participate in, we will continue these inequalities.

Case-in-point, most enterprise CMS vendors lack robust full-site content delivery network (CDN) integration. A few months back, I was pulled into a scenario where a business has been working with a leading CMS vendor to roll-out a network of multi-regional websites.
