Amazon Makes Virtual Private Clouds Its Default

Undoubtedly VMware and other cloud merchants won’t care much for this turn of events

Amazon has dropped more crumbs in the forest to entice the enterprise to ultimately abandon its own infrastructure for its doubtlessly cheaper public cloud.

It's making its Virtual Private Cloud (VPC), which used to be separate service, a free default.

It said in a blog that the announcement was so important "If you use or plan to use Amazon EC2, you need to read this post!"

Undoubtedly VMware and other cloud merchants won't care much for this turn of events.

Amazon is starting what it called its EC2-VPC roll-out in its regions in Sydney (Asia-Pacific) and São Paulo (South America). It'll branch out elsewhere in the next few weeks.

The free offer is only open to new customers and accounts that haven't used those regions before. Existing AWS customers can try the new stuff if they create a new AWS account or pick a region they haven't used before.

Amazon's Virtual Private Cloud (VPC) will be configured automatically when the user launches an EC2 instance or provisions Elastic Load Balancers, RDS databases or ElastiCache clusters like one normally would.

Amazon will launch the necessary resources and assign each EC2 instance a public IP address. Users can then assign multiple IP addresses to an instance, change security group membership on-the-fly and add egress filters to their security groups if they want.

Nobody's code has to be modified. The widgetry is designed to be compatible with the user's existing shell scripts, CloudFormation templates, Elastic Beanstalk apps and auto-scaling configurations.

Amazon makes a distinction between EC2-VPC and what it's now calling EC2-Classic, its more complicated, four-year-old way of setting up VPCs by creating a virtual network of logically isolated EC2 instances and an optional VPN connection to one's own data center.

Amazon has also added features to VPC like DNS hostnames, DNS name resolution, ElastiCache and RDS IP addresses.

It is also offering a third way to create a non-default VPC that isn't set up automatically.

Predicted by Gartner to add $1.9 trillion to the global economy by 2020, the Internet of Everything (IoE) is based on the idea that devices, systems and services will connect in simple, transparent ways, enabling seamless interactions among devices across brands and sectors. As this vision unfolds, it is clear that no single company can accomplish the level of interoperability required to support the horizontal aspects of the IoE. The AllSeen Alliance, announced in December 2013, was formed wi...
There’s Big Data, then there’s really Big Data from the Internet of Things. IoT is evolving to include many data possibilities like new types of event, log and network data. The volumes are enormous, generating tens of billions of logs per day, which raise data challenges. Early IoT deployments are relying heavily on both the cloud and managed service providers to navigate these challenges. In her session at 6th Big Data Expo®, Hannah Smalltree, Director at Treasure Data, to discuss how IoT, B...
Goodness there is a lot of talk about cloud computing. This ‘talk and chatter’ is part of the problem, i.e., we look at it, we prod it and we might even test it out – but do we get down to practical implementation, deployment and (if you happen to be a fan of the term) actual cloud ‘rollout’ today? Cloud offers the promise of a new era they say – and a new style of IT at that. But this again is the problem and we know that cloud can only deliver on the promises it makes if it is part of a well...

BlueData aims to “democratize Big Data” with its launch of EPIC Enterprise, which it calls “the industry’s first Big Data software to enable enterprises to create a self-service cloud experience on premise.” This self-service private cloud allows enterprises to create 100-node Hadoop and Spark clusters in less than 10 minutes. The company is also offering a Community Edition via free download. We had a few questions for BlueData CEO Kumar Sreekanti about all this, and here's what he had to s...
Labor market analytics firm Wanted Analytics recently assessed the market for technology professionals and found that demand for people with proficient levels of Hadoop expertise had skyrocketed by around 33% since last year – it is true, Hadoop is hard technology to master and the labor market is not exactly flooded with an over-abundance of skilled practitioners. Hadoop has been called a foundational technology, rather than ‘just’ a database by some commentators – this almost pushes it towards...
