UKFast Opens Trapdoor under prices, Thumbs nose at AWS

The UK offers UK accommodation UKFast lowered its prices for overnight accommodation Openstack said, taking a burst of AWS.

The lowest prices refer to the UKFast Flex eCloud platform and the company says it has lowered its prices by up to 44 percent. Several discounts are available for wholesale purchases, including 30 percent for customers who have a three-year contract.

"It was very good for our industry where AWS entered the market as it fosters innovation and forces around the world to develop their game," said CEO Laurence Jones.

"But it is easy in the business to become a victim of their own success and I believe AWS because of its size as it is unable to match the level of support provided by some of the smaller British hosts and cloud games."

Jones added: "There is a lot of confusion as to how certain elastic and null products have a price clients end up paying a lot more than they expected while hidden costs arose .."

Is not wrong. While UKFast put their bids on a price calculator on a page, Amazon has a multitude of calculators and a wide range of options to choose from.

ECloud Flex UKFast said in a statement, it allows developers to "build and generate individual virtual machines programmatically with all virtual hosting platforms with the provided OpenStack APIs."

"The popularity of Flex is not a surprise," said the company, "but it has allowed us to expand the product and now we pass on the benefits to our customers. The investments we have made in our data centers mean that we now offer the cloud to A more competitive price.

The big elephant in the room to choose AWS is the cost of network out or bandwidth. Up to 10 tons / month bandwidth of the public Internet network Amazon EC2 (London area) on demand will cost you $ 0.09 / GB - $ 180 per month if you use all 10TB - then charge that UKFast To 10 TB of public Internet network bandwidth is £ 32.00 / month or $ 39.71.

On the other hand, an AWS "hard disk" can be moved from one server to another. Additionally, AWS scales for self-efficacy, which makes it more or less perfectly the highest amount of NIS bar leaving your wallet.

AWS says a typo caused the massive S3 failure this week

Everybody makes mistakes. But working with Amazon Web Services means that incorrect entry can lead to a massive failure that will paralyze popular sites and services. This is apparently what happened earlier this week, when the AWS Storage (S3) service at the Northern Virginia vendor experienced a 11-hour system failure.




All other Amazon services in the US-ESTE-1 region that rely on S3, such as Elastic Block Store, Lambda, and the launch of a new forum to offer them the Elastic Compute Cloud service infrastructures have been impacted by the interruption.

AWS has apologized for the incident at an autopsy published Thursday. The blackout affected the likes of Netflix, Reddit, Imgur and Adobe. More than half of the 100 online shopping sites have experienced slower load times during the failure, according to APICA's monitoring service site.

Here is what caused the failure, and what Amazon plans:

According to Amazon S3 authorized employee has executed a command that was supposed to be "extracting a small number of servers from one of the subsystems S3 S3 that is used by the billing process" in response to the service of the billing processes running more Slow than expected. One of the parameters of the command was incorrectly entered and fired at a large number of servers that support a pair of S3 critical subsystems.

The subsystem handles metadata index and location information for all S3 objects within the region, while the inversion subsystem manages the allocation of new storage facilities and requires the index subsystem to function properly. Fault-tolerant, the number of servers stopped requires both a full reboot.

As it turns out, Amazon has not completely restarted these systems in their larger regions for several years, and S3 has experienced massive growth in the interim time. Restarting these subsystems has taken longer than expected, which added to the duration of the outage.

In response to this incident, AWS makes several changes to its internal tools and processes. The responsible for the failure tool has been modified to remove the slower servers and block transactions that have capacity below the control security levels. AWS also evaluates its other tools to ensure they have similar security systems.

AWS engineers will also begin refactoring the S3 index subsystem to help accelerate restarts and reduce the Blast Radius problems in the future.

The cloud service provider has also modified its dashboard health service dashboard to run in several regions. AWS employees were unable to update the dashboard during the crash because the S3 console depended on the affected area.

Amazon may launch new AWS productivity suite to take on Microsoft and Google

Amazon Web Services intends to consolidate its messaging, file storage and videoconferencing services into a productivity package that would compete with Microsoft and Google, according to a report released on Friday.

The sources said the information that AWS is still in the early stages of development with its productivity suite and has not been settled exactly what applications would be included. The company is working to update its current WorkDocs Workmail and to attract more corporate customers.

The combination of applications helps AWS to compete with Google and Microsoft Office Suite G 365. Companies that are currently working with AWS told the information that Amazon Services does not sell as well as they are currently less advanced than Google or Microsoft products .

Amazon is catching up with other productivity suites by adding the functionality of existing applications such as Workmail. In November, for example, AWS has added the ability to record all emails sent and received so that companies in the finance and health sectors can comply with compliance regulations.

Last week AWS announced the application of the doorbell that combines video conferencing, voice, chat and screen sharing. Adding this application as a whole could make Amazon's services as suites feature meeting places or similar Microsoft computers.

The information indicated that it is not yet clear whether the AWS result includes an online word processing application that allows for collaboration such as Google Docs. Amazon does not currently offer such a service, but a source said it could enter this territory with a recent update of the existing AppStream service.

There are no details about the cost of the Amazon productivity suite. Suite G Google starts at $ 5 per user per month, and Microsoft Office 365 starts at $ 6 per user per month. AWS currently charges $ 6 for Workmail and WorkDocs.

Domino's moves online ordering from AWS to Azure

The global migration of the OneDigital cloud begins.

Domino Pizza Rest counting down the days until the baseline control system begins taking pizza orders to a new Azure platform environment as a service in Australia.

The retailer has recently taken the decision to withdraw the OneDigital AWS system globally and transfer it to Microsoft's cloud technology.

Domino has used Amazon Web Services as a hosting partner for all of its critical systems over the past four years. It has a small number of systems - such as Exchange, which is currently moving to Office 365 - housed in a server room in Brisbane.

While most of its core platforms remain in AWS, last year the pizza chain decided to move its own OneDigital Microsoft Azure PaaS .NET platform into the world.

OneDigital is the online ordering platform that is used by all Domino markets worldwide to process orders.

Unlike Domino's infrastructure as a service with AWS, Azure PaaS offers the pizzeria chain support for the entire web application lifecycle through servers, storage and networking, as well as development tools, intelligence Business, middleware and database management.

"Going to PaaS, we believe we will be able to advance in our high regional availability, better contain our development costs - because we will be able to use many of the standard Azure services - the experience closer to users," said Wayne McMahon, the IOC to ITnews.

Each instance of the Domino OneDigital Region will be centrally organized, but all cases worldwide orders from one of Domino's regional operations.

"If such an A / NZ converter hit the nearest body [at home] and it was not available, it would go to the next closest available, and so on," McMahon said.

However, the retailer will ensure that orders in the areas where the rules on personal data protection are processed are processed locally and not to take risks with the privacy of the customer.

Domino Pizza Rest Australia and New Zealand are in the final test of Azure, with live orders "imminent" according to McMahon. Japan will change in the coming months, with European markets to follow.

The objective of the company is to be fully migrated at the end of the current fiscal year.

However, McMahon said there are no plans to move any of the other major pizza chain systems out of the AWS and Azure environment.

"AWS is still a very important partner for us. There is no compelling reason to move our other critical systems," he said.

"They do not necessarily benefit from PaaS."

Code cleanup

Domino has taken the opportunity to embark on an improvement program that consists of optimizing thousands of services associated with the OneDigital platform.

"We use the PaaS opportunity, not only by getting services and moving, but methodically through all the services to make sure it is not optimal," said McMahon.

The IT team began clearing the code and "finding better ways to do things" last September and has since completed the process.

Large pieces of work include the service layer rewrite since the SQL Server approval on AWS DocumentDB in Azure, McMahon said - "very important parts of our architecture that can be done with the price and good and how we are managing."

Snapchat signs $1bn cloud deal with AWS

Snapchat has an agreement with Amazon Web Services (AWS) to provide redundancy for its messaging platform, at a cost of $ 1 billion over the next five years.

Snap, the parent company's messaging-based photo messaging platform, already has an agreement with Google, spending $ 400 million a year on its cloud platform.

Snapchat has about 158 ​​million active users per day, but it works almost entirely in the cloud. It was one of the first prominent customers when Google agreed to its infrastructure-as-a-service offer in 2011.

In a presentation for an upcoming IPO, Snap revealed that it has also reached an agreement with Amazon to improve the redundancy service, taking its annual expenditure estimate into the cloud hosting of 450 million - more than the company obtained a Billing in 2016.

In the presentation, Snapchat said, "In March 2016, we concluded the AWS Enterprise contract for using cloud services from Amazon Web Services, Inc. or AWS, which was modified in March 2016 and again In February 2017. The agreement will continue indefinitely until it is terminated by either party.

"Under the addition of February 2017 for the agreement, we have committed to spend $ 1.0 billion between January 2017 and December 2021 AWS services (50.0 million in 2017, 125.0 million Dollars in 2018, $ 200.0 million in 2019, $ 275.0 million in 2020 and $ 350.0 million in 2021.) If the minimum purchase commitment of one year is not respected, we are required to pay the difference.

Snapchat also hinted that it could create its own infrastructure in the future in an attempt to reduce costs, adding: "In the future, we can invest in building our own infrastructure to better serve our customers.

AWS to Build Fourth Dublin Data Centre



Amazon announced the acquisition of a new site in Dublin where it will build another data center for the Irish cloud unit Amazon Web Services (AWS).

The multi-million dollar facility, which will be the fourth AWS data center in Dublin, will be installed in a former warehouse for storage and distribution of Barretts of the company. Located on the outskirts of Tallaght, south of Dublin, the new data center will be located very close to the other three facilities in Dublin, including a building under construction at the former Jacobs Cream Crackers biscuit factory.

Also in Tallaght it is the installation of AWS 22,300 square meters on the site of a former Tesco distribution center and a center converted into a factory formerly owned by Shinko Microelectronics.

After buying the Barretts site in late 2016, Amazon has already begun the construction process and asked for permission to demolish the building from the existing warehouse.

Local Dublin, Amazon is building a facility in Blanchardstown, where it already has two data centers. It is also building an additional center in Clonshaugh Business Park near Dublin Airport.

According to the Irish Independent, AWS investment in Ireland now stands at more than 1,000 million euros and the company is the largest provider of data center solutions in the country.

In addition to its expansion plans in Ireland, AWS announced the opening of a London area in the UK last year. The company said the new high availability region includes two different geographical areas, known as availability zones, each scheme meeting the Cyber Essentials Plus UK certification.

In addition, AWS offers all UK consulting clients on application development that are consistent with the principles of Cloud Security Center National Cyber Security in the UK and Compliance Compliance Governance reporting protocols on National Health (NHS).

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.
