Looking back at 10 years of compartmentalization at AWS

All Things Distributed

A concept that has changed infrastructure architecture is now at the core of both AWS and customer reliability and operations. By using zones, and failover mechanisms such as Elastic IP addresses and Elastic Load Balancing, you can provision your infrastructure with redundancy in mind. The calls used to launch and manage EC2 instances, fail over an RDS instance, or handle the health of instances behind a load balancer, all work within one zone.

The Business Case Justification for PaaS

Perficient - Digital Transformation

Consistency of architecture – Spring and Docker ecosystems, microservice patterns, etc. Operational services – security, logging, dynamic routing, load balancing, etc. It is best to consider both software development (full-lifecycle) and operational benefits together for the business case and also, more importantly, for the platform architecture requirements.

Vendor-Side DevOps Practices Can Still Deliver Better Value While Client-Side Government Processes Catch Up


Each cloud computing provider has “opinionated” ways of handling things such as load balancing, elastic scaling, service discovery, data access, and security to name just a few. Coupling container architectures such as Docker with a solid continuous delivery process can really supercharge your development teams in their application development and delivery. Cloud architectures hold great promise in the ability to promote applications to new heights in ubiquity and scale.

Lessons Learnt from Running a Container-Native Cloud

The cloud offers container-based services (load balancing, scheduled jobs, functions, etc.). The next couple of slides also focus exclusively on, and it appears that the majority of this session will be an advertisement for (instead of focusing on helping the OpenStack community understand how OpenStack components and architecture may be affected by the extensive use of containers within an OpenStack deployment).

database, app server) can dynamically configure an isolated “soft” network, complete with firewalls, load balancers, security policies, etc.     Although this is an explicit process today (sorry, no automated load balancing!)   On a more practical note, it’s nice to see the leap from airy architectural concepts to pragmatic, detailed reference architectures -- hardware, software and methodologies -- that can be put into production today.

Fountainhead: Differing Target Uses for IT Automation Types


A specific angle I want to address here is that of infrastructure automation ; that is, the dynamic manipulation of physical resources (virtualized or not) such as I/O, networking, load balancing, and storage connections - Sometimes referred to as "Infrastructure 2.0". a Fabric), and network switches, load balancers, etc. And, a single virtualized switching node can present itself as any number of switches and load balancers for both storage and network data.

The next step is to define in software the converged network, its switching, and even network devices such as load balancers. Provisioning of the network, VLANs, IP load balancing, etc. Gartner and others agree - this is the next wave in data center architecture.

Kubernetes on OpenStack: The Technical Details

Lees next provides an overview of the Kubernetes architecture (Kubernetes master node containing API server talking to controller manager and scheduler; kubelet, cAdvisor, and kube-proxy on the worker nodes; etcd as a distributed key-value store for storing state in the Kubernetes master; pods running on worker nodes and having one or more containers in each pod). Load balancing is the next connection point that Lees reviews.

Kubecon Liveblog: Opening Keynote

Scott Lowe

Burns demonstrates how Kubernetes makes this easier by showing a recorded demo of scaling Nginx web servers up to handle 1 million requests per second, and then updating the Nginx application while still under load. After the demo completes, Burns takes a few minutes to break down the architecture behind the demonstration. Loadbots,” managed by a Kubernetes replication controller, generated the load against an Nginx service, which in turn is backed by a number of Nginx instances.

Kubernetes, Kubeadm, and the AWS Cloud Provider

Scott Lowe

Whatever DNS name you supply for controlPlaneEndpoint —and it should be a DNS name and not an IP address, since in an HA configuration this value should point to a load balancer, and IP addresses assigned to AWS ELBs can change–will also be added as a Subject Alternative Name (SAN) to the API server’s certificate.

IDF 2014: Architecting for SDI, a Microserver Perspective

Scott Lowe

Once again this comes back to Intel’s rack-scale architecture work.) A traditional SRF architecture can be replicated with COTS hardware using multi-queue NICs and multi-core/multi-socket CPUs. Workloads are scheduled across these server/linecards using Valiant Load Balancing (VLB). Of course, there are issues with packet-level load balancing and flow-level load balancing, so tradeoffs must be made one way or another.

When Using Cloud Computing to Replicate is the Right Idea

Data Center Knowledge

With a well-planned deployment, and a good infrastructure, companies can efficiently load-balance their IT environment between multiple active, cloud-based, sites. So, if one site should go down – users would transparently be balanced to the next nearest or most available data center.

Liveblog: Scaling to Your First 10 Million Users

Scott Lowe

The next step is to add an Elastic Load Balancer (ELB) and distributing the application across two availability zones—this means 2 web instances and 2 instances of RDS (one active and one standby). This sort of architecture gets you greater scale as well as greater redundancy and fault tolerance. Further, the recently-announced Application Load Balancer (ALB) can offer content-based routing, container-based applications, WebSockets, and HTTP/2 support.

Challenges faced here led FanDuel to re-architect to the next-generation architecture. In 2011, FanDuel migrated entirely to AWS, but scaling issues due to application architecture persisted. In 2012, FanDuel moved the architecture toward SOA, introducing message queues to decouple services.
