How Amazon’s Cloud Infrastructure for VMware Could Find More Uses

One surprising thing in it that Amazon Web Services has to run VMware virtualization software in their own cloud data centers is the way ... a cloud as it seems.

Amazon collects masses of computers "bare metal", which, unlike other AWS servers, lack of virtualization. This is because the VMware software is built using its own flavor of virtualization and that, in turn, AWS had to offer VMware servers a phalanx stripped of Xen virtualization, which runs the rest of Amazon computers, known collectively Such as Elastic Compute Cloud, the EC2.

AWS as product manager Matt Wood explained to Fortune in November:

We have partnered with VMware to bring its existing software stack to EC2. Customers told us they wanted AWS benefits and VMware benefits, but did not want to run our hypervisor, so they worked on a new EC2 part that allows VMware to run natively on EC2.

Think of VMware as offering a sandwich with peanut butter and jelly using your customers' bread. Now the customer wants to use the Amazon Pan, except the bread Amazon offers comes with a feature peanut butter. Following this analogy, Amazon has agreed to demold the peanut butter many loaves so VMware can make sandwiches using its own PB formulation and in The bread of Amazon.

In theory, this means that all major commercial customers - and there are many - who use VMware (VMW, -0.45%) to manage their own data centers can more easily move their workloads to AWS data centers using the cloud of VMware for the AWS product. This is an interesting proposal for companies that just want to continue running their virtualized applications as it is, rather than re-jiggering to run on Amazon infrastructure.

Virtualization, which allows a set of hardware to run more than one set of tasks is a key element of cloud computing, so bare metal is considered a kind of Uncloudy.

When this bare metal job was announced in October, it was painted as a single VMware option. But there are potentially other great uses for these servers without AWS Xen. Bare metal, for example, tends to be faster than virtualized hardware for applications such as databases that send large amounts of data in and out of disk storage.

"There is also a growing trend to put the bare metal virtualization containers to save on licensing costs and overheads, but it is usually for the private cloud," said Sebastian Stadil, CEO of a Scalr management company Cloud. Containers are a modern means that software developers to package applications that can run almost anywhere.

Bare metal is also useful for older applications, but it remains important that it can not be virtualized, for various reasons, he points out. Obviously, others saw opportunities. IBM (IBM, + 0.25%) and Rackspace provide the bare metal with other options in the more densely virtualized cloud.

When asked if in November AWS had other potential uses for these bare metal servers, Madera responded that there was "nothing to announce at this time."

Opinion is mixed among observers if the AWS company parlay this bare metal capability beyond VMware or only use it as a way to attract VMware data centers and powerful Amazon customers as some suspect, try to move them completely Amazon Under VMware).

"It would be reasonable to assume that once these workloads arrive at AWS, it is interesting to start rearchitecturer some (perhaps all a day) to run natively on the AWS infrastructure without the overhead of a VMware license declares Paul Miller , Senior analyst at Forrester Research.

Sateesh Narahari, vice president of Managed Methods Products, a cloud security company, also views these instances of bare metal VMware "as a transitory state toward the full cloud."

It is possible that even AWS executive does not know what will happen. The giant cloud is nothing if it is not pragmatic. If Amazon (AMZN, -0.89%) sees VMware's unique opportunity for the AWS cloud materializes in the middle of 2017, it will be built.

"If AWS can run the economy and infrastructure management - and tend to be good at this - it seems likely that we will see an AWS offers generic bare metal sooner rather than later," said Miller Forrester.

Amazon’s AWS opens its first UK region in London

Last year, AWS of Amazon announced that it would launch a data center in the UK to the finals of 2016. It is now the end of 2016 and, according to its word, AWS has launched its London region) "To complement its existing European regions in Ireland and Frankfurt, that opened in 2007 and 2014.

In total, AWS now offers operates between 16 regions with a total of 42 zones of availability around the world. That is up from 11 regions only a year ago and a number that is likely to increase throughout of 2017. The new region in London will have two zones of availability.

London will offer all basic AWS services (think in EC2, S3, RDS, etc.). It is worth noting that some of the more advanced tools of AWS like Lambda and its announced machine learning services will not be available in London yet. Amazon's managed email, file storage, comparisons, and virtual desktop services portfolio is not yet available in London.

"With the launch of the AWS Europe (AWS), AWS can make a great deal of unreserved uk, public sector and startup clients reduce IT costs, in the data needs and undertake rapid transformations in areas Critics, Analysis and Internet of Things ", Amazon CTO Werner Vogels writes on his blog today.

Moving to the cloud requires (and attracts) scarce, expensive talent, say 3 big AWS users

The move to Amazon Web Services is proving costly for Matson, Honolulu based shipping company that last month announced that it has abandoned its four data centers in favor of going all-in with AWS. But spending does not come from the leasing of AWS computing and storage resources. Rather, it's from Matson's salary is to have to pay for IT employees and developers who know how to make the most of what AWS offers.
"We were surprised by the compensation required" to attract skilled employees, said Peter Weis, CIO of Matson, at a round table at Las Vegas last week. "But we have adjusted."

Raji Arasu, Senior Vice President of Platform and Services for Intuit Financial Software Maker, and Dominic Shine, Chief Information Officer for Media & Real Estate Corp.

While the one-hour session was held at an AWS event, with AWS Vice President of Global Sales Mike Clayville, the three executives spoke frankly, answering questions from a group of 150 journalists from all over the world. The execs provided some ideas that could help other organizations think about their cloud computing strategy.

It has been difficult to find trained people, especially those who are willing to work in a company that is certainly not "high tech" or "biotech but sailing around the world", even though Matson has its computer center in Oakland, Near San Francisco , He said. Finding the best people "was and still is my biggest focus of interest." But an advantage in moving to AWS, he said, is that "when you are known as an innovator and a builder, using this type of tools, you are playing in leagues A, and you attract people of grade A."

Conversely, said Shine of News Corp., "You will not get any A-grade developers if you offer the opportunity to develop traditional infrastructure. They will not want to work there.

News Corp., the Rupert Murdoch company that publishes The Wall Street Journal and owner of publisher of novels Harlequin Enterprises and Realtors.com real estate site, has closed 25 data centers in its passage in the cloud.

"We have set a goal of transferring 75% of our computing power to the public cloud in three years and saving $ 90 million," Shine said. "Three years later, we saved more than $ 100 million in avoided capital and about 65 percent in the cloud." It's really transformed the way we work. We can count on AWS to give us a reliable platform that continues to grow, and our technology Teams focus on product development for customers.

Arasu d'Intuit sounded a similar theme. "Sixty percent of our users are working on things like data proliferation, lack of standards, security of hardening and breaking down to monolithic core in services." AWS meets these needs, which attracts us because of the AWS engineers are becoming an extension of our team.

Turbo Tax and Payroll, was "very attractive" because these products "have a lot of seasonal peak, which means there are periods of the year where there are tons of traffic being carried to Them. "The ease of expansion and contracting computing power and storage in the cloud is therefore a key benefit, she said.

Moving to the cloud is not a decision to be made by the IOC of a company, said Matson Weis. "This is a CEO strategy, and the board needs to fully understand it." It is not a spectator sport. "Everyone can play, including the CEO." There has been a fundamental cultural shift in the business, and the result is that people do not Avoid computers. This has created a lot of teamwork and good morale. "

Matson's move to the cloud "has created an audacity, where the speed of ideas in the senior team has increased, as they know that the IT platform can manage it," he said.

The treatment of increased latency of interactive applications in the cloud, as opposed to internal data centers, has been "a very different art and science that needs to be developed within an organization," noted Arturo Intuit. "We continue to work on this."
