Carsales moves website into AWS

Auto ads Site Carsales has completed the migration of your website in the public cloud Amazon Web Services to achieve greater flexibility and to prepare for an active-active future.

The company is no stranger to public cloud services, after receiving your disaster recovery AWS for some time and its image in infrastructure for Microsoft Azure ago.

Until this month, the site Carsales was received in an establishment Hostworks.

But after being impressed by the performance of your disaster recovery environment in AWS Carsales it started there a year shifting your production environment in the same configuration described.

"Carsales used to be a monolith, which was basically a big piece of very tightly integrated code, and implementing the code once or twice a week," the group operations director Dmitry Carsales Kulchitsky said.

"In the last two years, we were on the way to microservices and the creation of a number of components: the Carsales site now consists of hundreds of parts that work independently most moving, but along with the other".

This meant that the company needs to ensure that any new platform could manage all these moving parts while being able to change the way Carsales wanted.

Earlier this month, efficient production and DR environments around reversed; the first is now in AWS and now is Hostworks DR.

While the actual migration that occurred in a day, Carsales engineers spent planning year, and testing and traffic are replicated to ensure the new infrastructure would be able to climb up and down and accept the amount of site traffic web is set to the maximum load.

Carsales decided to accept as its testing infrastructure in AWS, releasing about five or six locally hosted servers in the central office of the company.

The measure reduces test time of about an hour in minutes.

"What was important because we had much to do in so little time," director of quality assurance Scott Clements he said.
The test equipment for the preparation of production in four areas: performance, network security and scability.
Carsales imitating the production flow of traffic to the new environment, which showed an increase of 25 percent in the current production volumes.
"That gave us a lot of confidence in the new platform," Clements said.

future active-active

While the company was one of the earlier adopters of public cloud, Kulshitsky said Carsales only push workloads in such environments where it made sense.

"We realize that some have no place in the cloud, especially where there is no need for elasticity, we are very aware of it," he said.

All platforms that do not require elasticity Hostworks remain for now, he said, but Carsales engineers have their eyes on an active-active configuration in the next year.

"Our ultimate goal is to run an active-active to protect us from all problems in the regional center or data system," Kulshitsky said.

Before he can do that, the company will decide whether to maintain its fierce agnostic vendor or supplier standardization mentality would be more effective.

"We have two schools of thought about it," Kulshitsky said.

"Being with a vendor is easier in terms of ease of use, but do not like vendor lock-in, so we do agnostic cloud and have more than one provider?

"We quite like the way the Hostworks AWS and, for the moment, but in the long term, there is the temptation to standardize on a particular provider for simplicity. But then also be able to switch providers if Proposition best value ".

building abstraction layers was observed to enable its platforms to operate in any hosting provider could be the answer.

"It is difficult to run a Windows or Linux server Hostworks or AWS or Azure, there is sill a Windows or Linux server so you can talk to him in the same way," Kulshitsky said.

"We want our solution architect so that there is a layer of abstraction that speak directly to these components and minimize our dependence on one supplier."

Project Kratos Enables AWS Lambda Code to Run on Multiple Clouds

Iron provider of a message queue and a platform for job processing, announced Kratos project that can perform functions on multiple AWS cloud Lambda. Functions are executed within Iron.io containers that can be run on any underlying cloud infrastructure.

AWS Lambda is a service that allows developers to run code that is executed in response to events such as a downloaded image. The code consists of functions that act as event handlers.

When the event occurs, AWS is responsible for putting in place the necessary procedures to implement the code and scaled as needed. The developer is fully operational security details.

Kratos project provides a platform that aims to be an agnostic cloud by introducing another layer between the code and the infrastructure. This layer consists of containers that are customized for Iron.io. Lambda existing functions can operate within containers.

Iron plans to do the same for the functions of the Google cloud. Chad Arimura, CEO and co-founder Iron.io, had this to say about the role of Kratos in containers:

Kratos project has created tools of packing Lambda functions within a container. Even if you can not stand the exact lambda API functions can achieve the same thing using the parameters of Kratos, as Travis Reeder, CTO Iron.io.

Supports Java, Python and Node.js, AWS Lambda has existed since November 2014. Events can be generated from various data sources, such as Amazon S3 (for example, addition or modification of an object), Amazon Kinesis ( for example, connect the data stream) and Amazon DynamoDB (eg change log tables). AWS is responsible for setting the infrastructure manager level code is executed automatically.

The Lambda driver code can be written in an editor on the AWS console or downloaded as a zip file. The code uses AWS specific constructions and requires modifications to work with AWS infrastructure than then. Google recently announced a similar offering called functions of the cloud.

In Kratos Project, the containers are running proprietary components, so would not this lead to a lock-in with Iron.io platform? Arimura said:

Arimura added that "importers will be available to pack and easily transported lambda functions, but in the future will also include API support for real tool reuse" migrate existing Lambda functions to Kratos. Kratos will be a command line tool that takes care of packing, pushing and record functions of the platform Iron

Nice, the high-performance computing company Amazon just acquired, has a heck of a customer list

Market-leading public cloud Amazon Web Services (AWS) has acquired Nice, an Italian company with a web interface for planning and monitoring of high-performance computing (HPC) workloads. The software should really be something, because he took the use of a long list of companies.

It is therefore not surprising that Amazon will not interrupt the service much. As head of AWS evangelist he puts yesterday in a blog:

"The Nice team marks remain intact and continue to develop products and support EnginFrame Cloud Office (VTC) and visualization. Customers will continue to receive support and world-class services, reinforced with support from AWS team. In the future, Nice and AWS will work together to create better tools and services. "

Of course, better services will strengthen the offer HPC AWS, "and that is certainly important that AWS is competing with Microsoft Azure (which bought the company in 2014 GreenButton HPC), Google Cloud Platform and other clouds.

But the other main attraction of Nice is your customer list. More starry than some other recent acquisitions of AWS, including Amiato, AppThwack and ClusterK.

A sample of customers from Nice

• Airbus
• Alcatel
• Audi
• Bridgestone
• Bosch
• CERN
• Chevron
• ConocoPhillips
• Ericsson
• Ferrari
• Fiat
• Harvard Business School
• Hess
• Honda
• Jaguar Land Rover
• Lear
• Magellan Aerospace
• McLaren
• MD Anderson Cancer Center
• Motorola
• Northrop Grumman
• Raytheon
• Red Bull
• Siemens
• Suzuki
• Toyota
• Yale University

Now, Amazon is making money from these companies (if not already customers of AWS), because they will continue to use nice tools like EnginFrame interface, which has application templates that make it easier for less technical users put in running quickly. And it's easy to imagine the agreement to the deployment of large-scale work in HPC AWS servers.

But even with that said, Nice acquisition was not large enough to be significant; Amazon did not disclose terms of the agreement.

Belle began in 1996 and is based in the Italian town of Asti.
