Introduction: on Wiki someone posted "...For relatively small installations, pub/sub provides the opportunity for better scalability than traditional client-server, through parallel operation, message caching, tree-based or network-based routing, etc. However, as systems scale up to become datacenters with thousands of servers sharing the pub/sub infrastructure, this benefit is often lost; in fact, scalability for pub/sub products under high load in large deployments is very much a research challenge. " Does anyone have something to say regarding scaling Publish/subscribe models?

Introduction: WordPress.com hosts 300 servers in 5 different data centers. It's always useful to learn how large installations manage all their unruly children: Currently we Nagios for server health monitoring, Munin for graphing various server metrics, and a wiki to keep track of all the server hardware specs, IPs, vendor IDs, etc. All of these tools have suited us well up until now, but there have been some scaling issues. The post covers how these different tools are working for them and the comment section has some interesting discussions too.

Introduction: It is widely recognized that MySQL is the most popular database software in the world. Since its inception in 1995, there have been 11 million product installations around the world in a wide variety of markets. There are more installations of MySQL in use today than any other database architecture. From startup companies hoping to be the next Web2.0 poster child to large global enterprises, the MySQL database architecture has proven to be flexible, extendable, scalable, and more than capable of filling high-capacity database roles in very different venues.

Introduction: This is a guest post by Frédéric Faure (architect at Ysance ) on the differences between using a cloud infrastructure and building your own. Frédéric was kind enough to translate the original French version of this article into English. I’ve been noticing many questions about the differences inherent in choosing between a Cloud infrastructure such as AWS (Amazon Web Services) and a traditional physical infrastructure. Firstly, there are a certain number of preconceived notions on this subject that I will attempt to decode for you. Then, it must be understood that each infrastructure has its advantages and disadvantages: a Cloud-type infrastructure does not necessarily fulfill your requirements in every case, however, it can satisfy some of them by optimizing or facilitating the features offered by a traditional physical infrastructure. I will therefore demonstrate the differences between the two that I have noticed, in order to help you make up your own mind. The Fram

2 0.67113197 1127 high scalability-2011-09-28-Pursue robust indefinite scalability with the Movable Feast Machine

Introduction: And now for something completely different, brought to you by David Ackley and Daniel Cannon in their playfully thought provoking paper:  Pursue robust indefinite scalability , wherein they try to take a fresh look at neural networks, starting from scratch. What is this strange thing called indefinite scalability ? They sound like words that don't really go together: Indefinite scalability is the property that the design can support open-ended computational growth without substantial re-engineering, in as strict as sense as can be managed. By comparison, many computer, algorithm, and network designs -- even those that address scalability -- are only finitely scalable because their scalability occurs within some finite space. For example, an in-core sorting algorithm for a 32 bit machine can only scale to billions of numbers before address space is exhausted and then that algorithm must be re-engineered. Our idea is to expose indefinitely scalable computational power to program

Introduction: I've recently started working with a large company who is looking to take one of their heavily utilized applications and move it to Amazon Web Services. I'm not looking to start a debate on the merits of EC2, the decision to move to aws is already made (and is a much better decision than paying a vendor millions to host it). I've done my reasearch and I'm comfortable with creating this environment with one exception, scaling MySQL. I havent done much work with MySQL, i'm more of an Oracle guy up to now. I'm struggling to determine a way to scale MySQL on the fly in a way so that replication works, the server takes its proper place in line for master candidacy, and the apache servers become aware of it. So this is really three questions: 1. What are some proven methods of load balancing the read traffic going from apache to MySQL. 2. How do I let the load balancing mechanism know when I scale up / down a new Mysql Server? 3. How to alert the master of the new server and initiate

Introduction: Update 3: InfoQ's Big Architecture Up Front - A Case of Premature Scalaculation? twines several different threads on the topic together into a fine noose. Update 2: Kevin says the biggest problems he sees with startups is they need to scale their backend (no, the other one). Update: My bad. It's hard to sell scalability so just forget it. The premise of Startups and The Problem Of Premature Scalaculation and Don’t scale: 99.999% uptime is for Wal-Mart is that you shouldn't spend precious limited resources worrying about scaling before you've first implemented the functionality that will make you successful enough to have scaling problems in the first place. It's kind of an embodied life force model of system creation. Energy is scarce so any parasites siphoning off energy must be hunted down and destroyed so the body has its best chance of survival. Is this really how it works? If I ever believed this I certainly don't believe it anymore. The world has c

Introduction: You might have consistency problems if you have: multiple datastores in multiple datacenters, without distributed transactions, and with the ability to alternately execute out of each datacenter;  syncing protocols that can fail or sync stale data; distributed clients that cache data and then write old back to the central store; a NoSQL database that doesn't have transactions between updates of multiple related key-value records; application level integrity checks; client driven optimistic locking . Sounds a lot like many evolving, loosely coupled, autonomous, distributed systems these days. How do you solve these consistency problems? Siddharth "Sid" Anand of Netflix talks about how they solved theirs in his excellent presentation,  NoSQL @ Netflix : Part 1 , given to a packed crowd at a Cloud Computing Meetup .  You might be inclined to say how silly it is to have these problems in the first place, but just hold on. See if you might share some of their problems, before gettin

Introduction: Scale-Out is incrementally adding servers as needed to scale rather than buying larger servers. Here's the MySQL idea of what a scale-out architecture looks like: This MySQL article lists 5 problems to avoid when scaling out: Don't Think Synchronously . Introduce asynchronous communication, parallelization, and strategies to deal with approximate or slightly outdated data. Don't Think Vertically.   Scaling by bigger machines won't work. Plan on horizontal scaling and asynchronous architectures form the start which make it easy to add capacity on demand. Don't Mix Transactions with Business Intelligence. Transactions and analytics are inherently different. Separate out different types of data onto different databases. Avoid Mixing Hot and Cold Data. Static and fast changing data are inherently different. Separate out different types of data onto different databases. Don't Forget the Power of Memory.   Make data accessible in RA
