Are you an Indian AWS (Amazon Web Services) Cloud Customer? Do you want to adopt AWS Mumbai Region for your production? Then we have an analysis for you which will help you to decide whether to go for AWS Mumbai Region or not. In this blog, we’ll look at aspects like “cost comparison, services availability, S3 object download speed test, latency check, compliance” between near and famous regions. For those who are not familiar to AWS, a region in AWS is a term which describes a set of AWS resources within a geographic area. Each region contains multiple, isolated locations calledAvailability Zones (AZ). In June 2016, AWS announced Asia Pacific (Mumbai) Region as 13th AWS Region. Now, AWS provides 35 AZs across 13 regions globally. There are more than 75,000 India-based customers who are already using other AWS Regions to save costs, accelerate innovation, and widen their geographic reach in minutes. What does Mumbai region mean to all the hitherto existing customers or new customer?

CloudWatch Custom Metrics for Windows Server

Posted on June 2, 2016 by Richa Pathak | Comments(0)

It’s not rare that users having requirements of sending custom metrics to CloudWatch. These metrics can be application based or server based. There are different ways we can send these metrics to CloudWatch like writing a simple PowerShell script and scheduling it in Task Scheduler to run periodically. Alternate way to accomplish this, which I personally find very easy is by making simple changes in EC2ConfigService in your windows instance. ADVANTAGES: It is very easy to implement. There is no need to write scripts which sometimes can be really lengthy. Task Scheduler is not required which in turn can save memory. Most Importantly, margin of making error is very less. Let’s take an example that you want to send Free disk and Memory utilization metrics to CloudWatch. PREREQUISITES: EC2Config version should be 2.2.5 or later. Create IAM user with following permissions. IMPLEMENTATION: 1. RDP into your windows instance and from the Start menu, click All Programs, and then click EC2ConfigService Settings. 2. Enable CloudWatch Logs Integration and click OK. 3. Go to C:\Program Files\Amazon\Ec2ConfigService\Settings\AWS.EC2.Windows.CloudWatch.json and replace below code in the file. 4. Go to Control Panel\System and Security\Administrative Tools\Settings and restart EC2 Config service. And It’s done. You

5 Reasons why Multi-Cloud Disaster Recovery (DR) is the Only Real DR Strategy

Posted on March 14, 2016 by Bhavesh Goswami | Comments(1)

Disaster Recovery (DR) is an important aspect of any cloud deployment. In the words of Amazon’s CTO Vernal Vogel’s, “Everything fails, all the time”. It is possible that an entire data center or region of the cloud provider goes down. This has already happened to most cloud providers like Amazon AWS and Microsoft Azure and will surely happen again in future. Cloud providers like Amazon AWS and Microsoft Azure will readily suggest that you have a Disaster Recovery and Business Continuity strategy that spans across multiple regions, so that even if a single geographic region is down, you can continue working off of another region. This sounds good in theory, but there are several flaws in the methodology of using the same region of a single provider. Below are the 5 reasons why I am asserting that this Cross-Region DR will not be that effective. Alternatively, companies would be looking at Multi-Cloud DR where a different cloud provider is used for the DR strategy. 1) A single AWS Region failure might cause huge capacity crunch for other regions used as DR Many businesses in the USA will have their AWS infrastructure in AWS East coast region. Most of them will have their cross-region DR setup in
