Introduction: Wille Faler has created an excellent list of best practices for building scalable and high performance systems. Here's a short summary of his points: Offload the database - Avoid hitting the database, and avoid opening transactions or connections unless you absolutely need to use them. What a difference a cache makes - For read heavy applications caching is the easiest way offload the database. Cache as coarse-grained objects as possible - Coarse-grained objects save CPU and time by requiring fewer reads to assemble objects. Don’t store transient state permanently - Is it really necessary to store your transient data in the database? Location, Location - put things close to where they are supposed to be delivered. Constrain concurrent access to limited resource - it's quicker to let a single thread do work and finish rather than flooding finite resources with 200 client threads. Staged, asynchronous processing - separate a process using asynchronicity int

Introduction: For solutions take a look at: 7 Life Saving Scalability Defenses Against Load Monster Attacks . This is a look at all the bad things that can happen to your carefully crafted program as loads increase: all hell breaks lose. Sure, you can scale out or scale up, but you can also choose to program better. Make your system handle larger loads. This saves money because fewer boxes are needed and it will make the entire application more reliable and have better response times. And it can be quite satisfying as a programmer. Large Number Of Objects We usually get into scaling problems when the number of objects gets larger. Clearly resource usage of all types is stressed as the number of objects grow. Continuous Failures Makes An Infinite Event Stream During large network failure scenarios there is never time for the system recover. We are in a continual state of stress. Lots of High Priority Work For example, rerouting is a high priority activity. If there is a large amount

Introduction: In  5 Lessons We’ve Learned Using AWS , Netflix's John Ciancutti says one of the big lessons they've learned is to create less chatty protocols : In the Netflix data centers, we have a high capacity, super fast, highly reliable network. This has afforded us the luxury of designing around chatty APIs to remote systems. AWS networking has more variable latency. We’ve had to be much more structured about “over the wire” interactions, even as we’ve transitioned to a more highly distributed architecture. There's not a lot of advice out there on how to create protocols. Combine that with a rush to the cloud and you have a perfect storm for chatty applications crushing application performance. Netflix is far from the first to be surprised by the less than stellar networks inside AWS.  A chatty protocol is one where a client makes a series of requests to a server and the client must wait on each reply before sending the next request. On a LAN this can work great. LAN's are typically

Introduction: Now that we have the C10K concurrent connection problem licked, how do we level up and support 10 million concurrent connections? Impossible you say. Nope, systems right now are delivering 10 million concurrent connections using techniques that are as radical as they may be unfamiliar. To learn how it’s done we turn to Robert Graham , CEO of Errata Security, and his absolutely fantastic talk at Shmoocon 2013 called C10M Defending The Internet At Scale . Robert has a brilliant way of framing the problem that I’ve never heard of before. He starts with a little bit of history, relating how Unix wasn’t originally designed to be a general server OS, it was designed to be a control system for a telephone network. It was the telephone network that actually transported the data so there was a clean separation between the control plane and the data plane. The problem is we now use Unix servers as part of the data plane , which we shouldn’t do at all. If we were des

2 0.70697057 673 high scalability-2009-08-07-Strategy: Break Up the Memcache Dog Pile

Introduction: Update: Asynchronous HTTP cache validations . A proposed HTTP caching extension: if your application can afford to show slightly out of date content, then stale-while-revalidate can guarantee that the user will always be served directly from the cache, hence guaranteeing a consistent response-time user-experience. Caching is like aspirin for headaches. Head hurts: pop a 'sprin. Slow site: add caching. Facebook must have a lot of headaches because they popped 805 memcached servers between 10,000 web servers and 1,800 MySQL servers and they reportedly have a 99% cache hit rate. But what's the best way for you to cache for your application? It's a remarkably complex and rich topic. Alexey Kovyrin talks about one common caching problem called the Dog Pile Effect in Dog-pile Effect and How to Avoid it with Ruby on Rails . Glenn Franxman also has a Django solution in MintCache . Data is usually cached because it's too expensive to calculate for every hit. Maybe it's a gnarly S

3 0.70539981 174 high scalability-2007-12-05-Product: Tugela Cache

Introduction: Tugela Cache is a cache system like memecached, but instead of storing data just in RAM, it stores data in the file system using a b-tree. You trade latency in order to have a very large cache. It's useful for sites that have caching requirements that exceed their available memory. It uses the same wire protocol as memcached so it can be dropped in without a hassle. From the website: As large MediaWiki deployments may gain performance using Memcached, at some level cost of RAM to store all objects becomes too high. In order to balance resource usage and make more use of our Apache server disks, Tugela, the distributed cached on-disk hash database, has arrived. Tugela Cache is derived from Memcached. Much of the code remains the same, but notably, these changes: Internal slab allocator replaced by BerkeleyDB B-Tree database. Expiry policy management moved to external program tugela-expire Much statistics code made obsolete. An interesting point brought up in the comme

Introduction: We talked about  42 Monster Problems That Attack As Loads Increase . And in The Aggregation Collection  we talked about the value of prioritizing work and making smart queues as a way of absorbing and not reflecting traffic spikes. Now we move on to our next batch of strategies where the theme is conditioning , which is the idea of shaping and controlling flows of work within your application... Use Resources Proportional To a Fixed Limit This is probably the most important rule for achieving scalability within an application. What it means: Find the resource that has a fixed limit that you know you can support. For example, a guarantee to handle a certain number of objects in memory. So if we always use resources proportional to the number of objects it is likely we can prevent resource exhaustion. Devise ways of tying what you need to do to the individual resources. Some examples: Keep a list of purchase orders with line items over $20 (or whatever). Do not keep

2 0.99455851 878 high scalability-2010-08-12-Strategy: Terminate SSL Connections in Hardware and Reduce Server Count by 40%

Introduction: This is an interesting tidbit from near the end of the Packet Pushers podcast Show 15 – Saving the Web With Dinky Putt Putt Firewalls . The conversation was about how SSL connections need to terminate before they can be processed by a WAF ( Web Application Firewall ), which inspects HTTP for security problems like SQL injection and cross-site scripting exploits. Much was made that if programmers did their job better these appliances wouldn't be necessary, but I digress. To terminate SSL most shops run SSL connections into Intel based Linux boxes running Apache. This setup is convenient for developers, but it's not optimized for SSL, so it's slow and costly. Much of the capacity of these servers are unnecessarily consumed processing SSL. Load balancers on the other hand have crypto cards that terminate SSL very efficiently in hardware. Efficiently enough that if you are willing to get rid of the general purpose Linux boxes and use your big iron load balancers, your server count c

3 0.99412024 911 high scalability-2010-09-30-More Troubles with Caching

Introduction: As a tasty pairing with Facebook And Site Failures Caused By Complex, Weakly Interacting, Layered Systems , is another excellent tale of caching gone wrong by Peter Zaitsev, in an exciting twin billing: Cache Miss Storm and  More on dangers of the caches . This is fascinating case where the cause turned out to be software upgrade that ran long because it had to be rolled back. During the long recovery time many of the cache entries timed out. When the database came back, slam, all the clients queried the database to repopulate the cache and bad things happened to the database. The solution was equally interesting:  So the immediate solution to bring the system up was surprisingly simple. We just had to get traffic on the system in stages allowing Memcache to be warmed up. There were no code which would allow to do it on application side so we did it on MySQL side instead. “SET GLOBAL max_connections=20” to limit number of connections to MySQL and so let application to err when i

4 0.99298233 836 high scalability-2010-06-04-Strategy: Cache Larger Chunks - Cache Hit Rate is a Bad Indicator

Introduction: Isn't the secret to fast, scalable websites to cache everything ? Caching, if not the secret sauce of many a website, is it at least a popular condiment. But not so fast says Peter Zaitsev in Beyond great cache hit ratio . The point Peter makes is that we read about websites like Amazon and Facebook  that can literally make hundreds of calls to satisfy a user request. Even if you have an awesome cache hit ratio, pages can still be slow because making and processing all those requests takes time. The solution is to remove requests all together . You do this by caching larger blocks so you have to make fewer requests.  The post has a lot of good advice worth reading: 1) Make non cacheable blocks as small as possible, 2) Maximize amount of uses of the cache item, 3) Control invalidation, 4) Multi-Get.
