Viber Media, provider of iPhone and Android apps that let users talk and text for free over 3G and Wi-Fi networks, is built upon a foundation of the MongoDB NoSQL database running atop the Amazon Web Services cloud.
A press release issued Tuesday by commercial MongoDB entity 10gen explains how Viber’s service works and how its infrastructure operates: Viber enables users to talk and text for free with other Viber users without having to sign up, create a separate account, or log in. Once the app is launched, the user simply enters his or her cell number and is automatically part of the community. MongoDB manages the intercommunity data exchange that enables users to call and text one another. Each time a Viber user connects a cell phone to the network, MongoDB receives call-related information. AWS Start-Up Challenge 2011 Finalists and Semi-Finalists. Here’s a quick quiz: What does a social gaming site for young women have in common with a cancer research app?
Not sure? Then how about this: What does a mobile video app have in common with a car sharing service? 2013/02/26/skype-competitor-viber-hits-175-million-users-up-from-140-million-in-december/ Messaging startup Viber, which lets users of most smartphone platforms send free texts, calls and messages via its app, is continuing to ramp up its user-base.
Speaking at the Mobile World Congress trade show in Barcelona today, CEO Talmon Marco announced the startup now has 175 million users. Viber has been around since early 2011, but growing rapidly in the past 12 months. In December it passed 140 million users, saying it was adding new users at a rate of 400,000 per day. Back in September, it hit 100 million users, after hitting 70 million users in May and 50 million in February.
Viber’s app supports iOS, Android, S40, Symbian, Windows Phone and BlackBerry. The messaging space is very fragmented globally, but for some context, Line — a messaging app popular in Japan — passed the 100 million user mark last month. AWS 아키텍처 센터. Amazon’s physical hardware and EC2 compute unit « Huan Liu's Blog. Ever wonder what hardware is running behind Amazon’s EC2?
Why would you even care? Well, there are at least a couple of reasons. Top 10 Things to Know About Amazon RDS - So you’ve finally caught on with the hype, and you’re seriously considering using Amazon RDS for your database needs.
Here are ten things you ought to know before you take the leap: 10. Amazon RDS uses a patched version of MySQL 5.1.38. While several discussions within MySQL forums allude to a growing concern that Amazon may not have the required expertise for upgrading and maintaining patched versions of MySQL, the fact still remains that Amazon has enough resources to just buy them from other vendors who do. The patch enables MySQL to scale dynamically in the cloud, besides adding other features. 9. 8. 7. 6. 5. 4. 3. Amazon ec2 - How to download an EC2 X.509 certificate with an IAM User account. Amazon SQS vs. RabbitMQ » NSONO.NET. Heads Up: This post is quite old.
Friends don't let friends make business decisions based on four-year-old blog posts. We've been using Amazon SQS where I work for awhile. We have a fairly heavy (though, that's relative: we're a small company) cloud application that makes use of a bunch of the Amazon services (SimpleDB, S3, EC2) and, when we needed a message queue, SQS was just there for us. It was convenient, simple, and reasonably quick to code at. Our application has now grown to a point where 'convenient' doesn't quite cut it anymore. Here's the core problem: with Amazon SQS, the message consumer is forced to poll the queue in order to determine whether or not a message is available. Cloud Database. Architecting Scalable Applications in the Cloud.
As an architect in the Professional Services group, I get the opportunity to talk to a lot of RightScale customers.
And I enjoy it very much since I get to learn about all their cool new ideas and the technologies and applications they are bringing to the cloud. Over the course of the last several years and hundreds of customer conversations, a few common threads of discussion always come up. Best Practices in Evaluating Elastic Load Balancing : Articles & Tutorials. Abstract To best evaluate Elastic Load Balancing you need to understand its architecture.
This article describes the features and unique architecture of the Amazon Web Services (AWS) Elastic Load Balancing service. It provides you with best practices, so that you can avoid common pitfalls when you test and evaluate Elastic Load Balancing. The intended audience for this whitepaper is developers who have minimal experience using Elastic Load Balancing, but it will be especially relevant if you have used software or hardware load balancers in the past.
Overview of Elastic Load Balancing Elastic Load Balancing automatically distributes incoming application traffic across multiple Amazon Elastic Compute Cloud (Amazon EC2) instances. You can build fault tolerant applications by placing your Amazon EC2 instances in multiple Availability Zones. Elastic Load Balancing also detects the health of EC2 instances. The “Elastic” in “Elastic Load Balancing”: ELB Elasticity and How to Test it. Update March 2012: Amazon published their own official guide to ELB’s architecture and building and testing applications that use it.
The official material is very consistent with the presentation offered here, more than two and a half years prior. Elastic Load Balancing is a long-anticipated AWS feature that aims to ease the deployment of highly-scalable web applications. Let’s take a look at how it achieves elasticity, based on experience and based on the information available in the AWS forums (mainly this thread). Netflix가 가지고 있는 기술과 문화.

The original CPU performance metrics did not accurately depict performance on multi-core servers.
The updated post utilizes an improved method of calculating CPU performance that applies more weight to multi-core aware benchmarks (see benchmarks description below for more info). Over the past couple of months we've spent some time benchmarking about 150 different cloud server configurations with 20 different vendors. Fast Forward - Provisioned IOPS for EBS Volumes. The I/O ImperativeAs I noted earlier this month, modern web and mobile applications are highly I/O dependent, storing and retrieving lots of data in order to deliver a rich and personalized experience. In order to give you the I/O performance and the flexibility that you need to build these types of applications, we've released several new offerings in the last few months: For seamless, managed, scaling of NoSQL workloads, we recently introduced DynamoDB, an SSD-backed NoSQL database with read and write times measured in single-digit milliseconds, with very modest variance from request to request.
DynamoDB makes it easy to scale up from 20 to 200,000 or more reads and writes per second and to scale back down again based on your application's requirements.
