Amazon Virtual Private Cloud (VPC) now allows customers to expand their existing VPCs

Amazon Virtual Private Cloud (VPC) now allows customers to expand their VPCs by adding secondary IPv4 address ranges (CIDRs) to their VPCs. Customers can add the secondary CIDR blocks to the VPC directly from the console or by using the CLI after they have created the VPC with the primary CIDR block. Similar to the primary CIDR block, secondary CIDR blocks are also supported by all the AWS service

How can I know if NAT instance is becoming a bottleneck

I'm running my own NAT instance inside of an AWS VPC. I want to make sure that the NAT instance will not be a bottleneck and to that end would like to set my own expectation for when to scale to a secondary NAT (if ever). I understand that instance type (currently an m1.medium if that's important) is an important aspect of this but would like to know how to check that the NAT instance is starting

25 Best Practice Tips for architecting your Amazon VPC

According to me Amazon VPC is one of the most important feature introduced by AWS. We have been using AWS from 2008 and Amazon VPC from the day it was introduced and i strongly feel the customer adoption towards AWS cloud gained real momentum only after the introduction of VPC into the market. Amazon VPC comes with lots of advantages over the limitations faced in Amazon Classic cloud like: Static

EC2 to VPC: A transition worth doing. - Engineering at Kiip

Kiip recently completed a migration from EC2 to VPC. VPC exited beta and became generally available in all regions in August, and allows you to provision compute nodes within a virtual network in AWS. For anything more than simple websites, we believe migrating to VPC is something worth doing, or at the very least worth investigating. Because Amazon VPC is a new service and requires a substantial

Amazon VPCを使ったミニマム構成のサーバ環境を構築する | DevelopersIO

よく訓練されたアップル信者、都元です。AWSにおいては、ネットワーク環境をあまり気にせず、数クリックで簡単にサーバを構築できるのは一つのメリットだと言えます。しかし、本格的に運用するシステムに関しては、ネットワーク環境をコントロールする需要も出てきます。AWS Virtual Private Cloud (VPC)を使えば、AWS上に仮想ネットワークを定義し、その上に各種サーバを配置することができます。深く考えずに非VPC環境に構築してしまったAWSサーバ環境は、簡単にはVPC環境に移行することはできません。従って弊社では、小さなシステムであっても、最初からVPC環境にシステムを構築することを推奨しています。「非VPCが許されるのは小学生までだよねー」とボスが申しておりました。かといって、ネットワークの構成をゼロから考えて構築するのもひと苦労であるため、本エントリーでは、システムの初期段
