A Beginner's Guide to Edge Computing

A Beginner's Guide to Edge Computing

There is a recent trend in change in architecture of the way data is stored and compute is done. Edge computing is one of such phenomena in which either the data or the compute is decentralized and taken to the nearest nodes of the user it can either be smartphone or local region servers.

In this blog we will delve into what Edge Computing really is, it’s various types, and see how it is implemented and managed in the real world.

Deploy serverless, event-driven Python applications using Zappa

Deploy serverless, event-driven Python applications using Zappa

Zappa makes it super easy to build and deploy server-less, event-driven Python applications (including, but not limited to, WSGI web apps) on AWS Lambda + API Gateway. Think of it as "serverless" web hosting for your Python apps. That means infinite scalingzero downtimezero maintenance - and at a fraction of the cost of your current deployments!

This blog acts a simple tutorial to deploy a sample Django/Python application using Zappa.

Demystifying High Availability in Kubernetes using Kubeadm

Demystifying High Availability in Kubernetes using Kubeadm

Kubernetes allows deployment and management container-based applications at scale. One of the main advantages of Kubernetes is how it brings greater reliability and stability to the container-based distributed application, through the use of dynamic scheduling of containers.  But, how do you make sure Kubernetes itself stays up when a component or its master node goes down?

In this blog we look at the steps to ensure that your kubernetes cluster is always highly available and fault tolerant.

Exploring Upgrade Strategies for Stateful Sets in Kubernetes

Exploring Upgrade Strategies for Stateful Sets in Kubernetes

In the age of continuous delivery and agility where the software is being deployed 10s of times per day and sometimes per hour as well using container orchestration platforms, a seamless upgrade mechanism becomes a critical aspect of any technology adoption. In this blog we explore the various upgrade strategies available for Statefulsets in Kubernetes with Cassandra as the database.

Continuous Deployment with Azure Kubernetes Service, Azure Container Registry & Jenkins

Continuous Deployment with Azure Kubernetes Service, Azure Container Registry & Jenkins

This blog talks about Azure's Kubernetes as a Service offering - AKS. I came across various issues while setting up AKS and its container registry so wanted to share some gotchas.

Finally, this blog provides the steps to setup continuous deployment pipeline with Azure Kubernetes Service, Azure Container Registry & Jenkins.

Machine Learning for your Infrastructure: Anomaly Detection with Elastic + X-Pack

Machine Learning for your Infrastructure: Anomaly Detection with Elastic + X-Pack

We need a practical and scalable approach to understand the cause-effect relationship between data sources and events across complex infrastructure of VMs, containers, networks, micro-services, regions, etc. Machine learning is particularly useful for such problems where we need to identify “what changed”, since machine learning algorithms can easily analyze existing data to understand the patterns, thus making easier to recognize the cause. This is known as unsupervised learning, where the algorithm learns from the experience and identifies similar patterns when they come along again.

Let's see how you can setup Elastic + X-Pack to enable anomaly detection for your infrastructure & applications.

A practical guide to deploying multi-tier applications on Google Container Engine (GKE)

A practical guide to deploying multi-tier applications on Google Container Engine (GKE)

In this blog, we look at how to deploy, scale & delete a Multi-tier (Flask/Python and MySQL) Application in Google Container Engine.

Surviving & thriving in the age of software accelerations

Enterprises need to adopt a new approach to software development and digital innovation. At Velotio, we are helping customers to modernize and transform their business with all of the approaches and best practices listed here in this blog. We talk in detail about how to achieve agility, cloud native development, DevOps maturity, micro-services adoption, digital transformation and build intelligent applications using data science in a secure environment.

A Primer on HTTP Load Balancing in Kubernetes using Ingress on Google Cloud Platform

A Primer on HTTP Load Balancing in Kubernetes using Ingress on Google Cloud Platform

Containerized applications and Kubernetes adoption in cloud environments is on the rise. One of the challenges while deploying applications in Kubernetes though is exposing these containerised applications to the outside world. This blog explores different options via which applications can be externally accessed with focus on  Ingress - a new feature in Kubernetes that provides an external load balancer. This blog also provides a simple hand-on tutorial on Google Cloud Platform (GCP).  

Container Security: Let's secure your enterprise container infrastructure!

Containerized applications are becoming more popular with each passing year. A reason for this rise in popularity could be the pivotal role that they play in Continuous Delivery by enabling fast and automated deployment of software services. Security still remains the major concern mainly because of the way container images are being used. This blog provides an answer to the below concerns:

  • There are so many docker images readily available on dockerhub, but are you sure the one that you are using is not injecting any vulnerability into your environment?
  • Do you know where your containers come from?
  • Are your developers downloading container images and libraries from unknown and potentially harmful sources?
  • Do the containers use third party library code that is obsolete or vulnerable?

Flannel: A Network Fabric for Containers

Containers are a disruptive technology and is being adopted by startups and enterprises alike. Whenever a new infrastructure technology comes along, two areas require a lot of innovation - storage & networking. Anyone who is adopting containers would have faced challenges in these two areas.

Flannel is an overlay network that helps to connect containers across multiple hosts. This blog provides an overview of container networking followed by details of Flannel.

Cloud Native Applications — The Why, The What & The How.

Cloud Native Applications — The Why, The What & The How.

Cloud-native is an approach to build & run applications that can leverage the advantages of the cloud computing model — On demand computing power & pay-as-you-go pricing model. These applications are built and deployed in a rapid cadence to the cloud platform and offer organizations greater agility, resilience, and portability across clouds.

This blog explains the importance, the benefits and how to go about building Cloud Native Applications.
