We use EBS volumes for persistent storage. To ensure we do not lose data and take backup regularly, AWS provides mechanism to take snapshot. Learn more on how to snapshot an EBS volume. In this guide, we will show, how to automate snapshots for an AWS EBS volume by schedule an automatic cron job. We will use Linux instance and see how to automate the snapshot using cronjobs.
AWS cloud products facilitate the way you can easily and in a reasonable time, deploy a scalable online service on Amazon cloud infrastructure. The slides include schemes that deal with the different cloud aspects such as elasticity, performance and security. The architectures demonstrated uses some advanced AWS products such as Auto-scaling, RDS, Route53 and much more. The presentation is a bit long, take your time and you will find these AWS features that can help you understand how to get more of your AWS cloud account.
The presentation includes great overview on why and how to monitor an online application running on a cloud infrastructure. It is based on the author extensive experience running a high traffic real estate portal on AWS cloud infrastructure. In the presentation you will find a list of the different types of monitoring layers from the underlying infrastructure all the way up the application stack.
Summary of past Cassandra benchmarks performed by Netflix and description of how Netflix uses Cassandra interspersed with a live demo automated using Jenkins and JMeter that created two 12 node Cassandra clusters from scratch on AWS, one with regular disks and one with SSDs. Both clusters were scaled up to 24 nodes each during the demo.
This presentation brought to you by Adrian Cockcroft, Director, Cloud Architecture at Netflix Inc.

S3Sync is a tool written in Ruby to synchronize system folders (EBS) and S3 buckets. In this guide we will shown you how to sync your EBS data with S3 bucket and vice versa.
We will run an EBS-backed Linux instance and sync data between our instance and S3 bucket.
To execute the S3Sync from your instance, you need Ruby (version 1.8.7 or above ) installed in your local machine. If you are running a Windows instance, download and install Ruby from http://rubyinstaller.org/downloads/ for a Windows local machine.
WordPress is one of the most popular open source blog platforms out there. It is used to power anything from simple blogs to complex portals, thanks to the variety of plugins the community has developed.
In this article we will describe the architecture options for deploying WordPress in AWS with scalability and high availability in mind. We will take advantage of the elasticity of the cloud and use more servers when we need them and less when we don’t (auto-scaling).
It happened again… this was the second AWS outage in the same month. Did you fail to protect your service online? Don’t forget – you can’t pass your liability onto your IaaS vendor.
You can find a great amount of knowledge resources with regards to AWS cloud High Availability architectures in Newvem’s resources center, starting from Best Practice for High Availability Deployment all the way to knowing more about how to maintain availability for your specific environment, such as how to maintain a failover to MSSQL DB server, or a case study on how to replicate PostgreSQL DB Between AWS Regions.
Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. Amazon Cloud Computing is a good choice if you want to deploy a very large scale network on the cloud that requires high availability, auto scaling and load balancing features.
This article is a quick introduction on designing to achieve High Availability (HA) with your AWS infrastructure architecture. We’ll start with a simple (and vulnerable) architecture design and work our way up to a complex multi-region setup. How far you go up these steps is up to you, depending on your uptime requirements (or SLAs) and budget.
In this article I describe how we created a redundant PostgreSQL database on the Amazon cloud using EBS snapshots as backups to deploy a PostgreSQL DB server DR mobile application for one of our customers.
PostgreSQL 9.1 includes new capabilities for asynchronous fast replication syncing between master and slaves. The master server streams new data to the current available slave. This version includes great improvements that generated significant fast WAL (Write Ahead Log) processing, which generates replication and fast launching capabilities for the slave servers.
