1 NET MVC, Cloud Scale & Deployment shows an interesting alternative approach for a Windows stack using ServerPath/GoGrid for a dedicated database machine, elastic VMs for the front end, and a free load balancer. [sent-2, score-0.363]
2 In this era of multi-core, large RAM machines and advances in parallel programming techniques , scale up is still a viable strategy and shouldn't be tossed aside just because it's not cool anymore. [sent-17, score-0.328]
3 com The Stats 16 million page views a month 3 million unique visitors a month (Facebook reaches 77 million unique visitors a month) 6 million visits a month 86% of traffic comes from Google 9 million active programmers in the world and 30% have used Stack Overflow. [sent-23, score-0.3]
4 When renting hardware nobody pays list price for RAM upgrades unless you are on a month-to-month contract. [sent-64, score-0.214]
5 It makes even more sense if you need to be able to scale on demand (add and remove machines as load increases / decreases). [sent-72, score-0.215]
6 Separate application and database duties so each can scale independently of the other. [sent-76, score-0.245]
7 Applications should keep state in the database so they scale horizontally by adding more servers. [sent-78, score-0.319]
8 The problem with a scale up strategy is a lack of redundancy. [sent-79, score-0.223]
9 So by starting scale up and gradually going scale out with non-open source software you can be in a world of financial hurt. [sent-86, score-0.324]
10 Markus Frind of Plenty of Fish fame is often used as a Microsoft stack poster child, but since he explicitly uses as little of the stack as possible he's not really a good example. [sent-96, score-0.56]
11 It's hard to separate out the Microsoft stack and the scale up approach because for licensing reasons they tend to go together. [sent-98, score-0.527]
12 If you find yourself in the position of transitioning from scale up to scale out by adding dozens of cores, MS licensing will bite you. [sent-99, score-0.483]
13 So for a scale up solution a Microsoft stack works, especially if you are already Windows centric. [sent-108, score-0.442]

15 If you aren't confused and if your head doesn't hurt after reading all that then you haven't properly understood the material :-) The Scale Up Badge was awarded because Stack Overflow uses a scale up strategy to meet their scaling requirements. [sent-114, score-0.274]
16 When they reach a limit they scale vertically by buying a bigger machine and adding more memory. [sent-115, score-0.236]

Introduction: A lot has happened since my first article on the Stack Overflow Architecture . Contrary to the theme of that last article, which lavished attention on Stack Overflow's dedication to a scale-up strategy, Stack Overflow has both grown up and out in the last few years. Stack Overflow has grown up by more then doubling in size to over 16 million users and multiplying its number of page views nearly 6 times to 95 million page views a month. Stack Overflow has grown out by expanding into the Stack Exchange Network , which includes Stack Overflow, Server Fault, and Super User for a grand total of 43 different sites. That's a lot of fruitful multiplying going on. What hasn't changed is Stack Overflow's openness about what they are doing. And that's what prompted this update. A recent series of posts talks a lot about how they've been handling their growth: Stack Exchange’s Architecture in Bullet Points , Stack Overflow’s New York Data Center , Designing For Scalability of Manageme
Introduction: We've had a few articles on the StackOverlflow Architecture and Stack Overflow Architecture Update - Now at 95 Million Page Views a Month . Time for another update. This time from a podcast. Every week or so Jeff, Joel and guests sit around and converse. The result is a podcast . In a recent podcast they talked about some of their recent architecture issues, problems, and updates. And since I wrote this article before my vacation, they've also published a new architecture update article: The Stack Exchange Architecture – 2011 Edition, Episode 1 . My overall impression is they are in a comfortable place, adding new sites, adding new features, making a house a home. Notable for their scale-up architecture, you might expect with their growth that they would slam into a wall. Not so. They've been able to scale-up the power of individual servers by adding more CPU and RAM. SSD has been added in some cases. Even their flagship StackOverflow product runs on a single server. New mac

Introduction: The most common complaint against NoSQL is that if you know how to write good SQL queries then SQL works fine. If SQL is slow you can always tune it and make it faster. A great example of this incremental improvement process was written up by StackExchange's Sam Saffron, in A day in the life of a slow page at Stack Overflow , where he shows through profiling and SQL tuning it was possible to reduce page load times from 630ms to 40ms for some pages and for other pages the improvement was 100x. Sam provides a lot of wonderful detail of his tuning process, how it works, the thought process, the tools used, and the tradeoffs involved. Here's a short summary of the steps: Using their mini-profiler it was shown that a badge detail page was taking 630.3 ms to load, 298.1 ms of that was spent on SQL queries, and then the tool listed the SQL queries for the page and how long each took. From the historical logs, which are stored in HAProxy on a month-by-month basis, Sam was able t

Introduction: We are on the edge of two potent technological changes: Clouds and Memory Based Architectures. This evolution will rip open a chasm where new players can enter and prosper. Google is the master of disk. You can't beat them at a game they perfected. Disk based databases like SimpleDB and BigTable are complicated beasts, typical last gasp products of any aging technology before a change. The next era is the age of Memory and Cloud which will allow for new players to succeed. The tipping point will be soon. Let's take a short trip down web architecture lane: It's 1993: Yahoo runs on FreeBSD, Apache, Perl scripts and a SQL database It's 1995: Scale-up the database. It's 1998: LAMP It's 1999: Stateless + Load Balanced + Database + SAN It's 2001: In-memory data-grid. It's 2003: Add a caching layer. It's 2004: Add scale-out and partitioning. It's 2005: Add asynchronous job scheduling and maybe a distributed file system. It's 2007: Move it all into the cloud. It's 2008: C

Introduction: We will be developing an RIA that will have a lot of database access. Think something like a QuickBooks but with about 50 transactions entered per hour per user. Users will be in the system for 7 to 9 hours a day and there will be around 20,000 users, all logged in at the same time. Reporting will be done just like a QuickBooks style app plus a lot of extra things you don't do in QuickBooks. Our operations is familiar with W2003 Server and MS SQL Server so they are recommending we stick with that. I originally requested Linux and PostgreSQL. How far can a single database server get me? If we have a 4 processor, 8 core, 128gb server, how far am I going to get before I need to shard or do something else? I know there are a lot of factors involved but in general for this size of a site, what should the strategy be? I've read almost all articles on this website but most of the applications are not RIA type of apps with this type of usage or they are architectures for

We fully hope and expect that Go becomes the standard back-end language at Google over the next few years. On GAE Go can load from a cold start in 100ms and the typical instance size is 4MB.
