amazinx introduction (image server with aws & nginx)

2. AWS + Cloud service - IaaS & PaaS + So many solutions - ELB (Elastic Load Balancer) : vertual server - EC2 (Elastic Compute Cloud) - S3 (Simple Storage Service) - RDS (Relational Database Service) - Route 53 : DNS system - SWF (Simple Workflow Service) … + Easy to Use anytime you want - just make an account, then click some on Management Console (you can make a program to avoid such operations)

3. GUI

4. EC2 instances + Micro ($0.027 / h) 613 MB memory Up to 2 EC2 Compute Units (for short periodic bursts) I/O Performance: Low +… + Cluster compute eight extra large ($2.400 / h) 60.5 GB of memory 88 EC2 Compute Units (2 x Intel Xeon E5-2670 , eight-core "Sandy Bridge" architecture) 3370 GB of instance storage I/O Performance: Very High (10 Gigabit Ethernet) (6000 yen / month for full “personal” use, we can get the relevant VPS for 1000yen /month, I guess. )

5. Free Tier + new AWS user can get these free use each month for one year - 750 hours of EC2 Micro instance usage - 750 hours of Elastic Load Balancing plus 15 GB data processing - 30 GB of Amazon Elastic Block Storage (EBS) plus 2 million IOs and 1 GB snapshot storage -… + So, without any payment, you can run - 1 Micro instance for a full year without stop or - 4500 Micro instance for 10 min / every month Why don’t u try it ? Getting Started Guide AWS Free Usage Tier http://docs.amazonwebservices.com/gettingstarted/latest/awsgsg-freetier/TestDriveFreeTier.html

6. Nginx + HTTP and reverse proxy server (also supports SMTP, POP3, IMAP) + aiming high performance - low memory usage - simultaneous connection - asynchronous event driven server (like Lighttpd) not thread or process oriented + limited functions - no Dynamic Shared Object of Apache

7. remarks “Apache is like Microsoft Word, it has a million options but you only need six. Nginx does those six things, and it does five of them 50 times faster than Apache.” - Chris Lea @ WordCamp SF 2008

8. performance + at certain situation (just copied from the site...orz) - CENTOS 5.1 - Dual 2.4GHz Xeon CPUs - 4GB RAM - RAID5 (4 x 15k disks) - Server and test client were connected via a consumer grade 10/100 switch - Keepalive turned on and with timeout of 15 seconds - GZIP turned on Apache vs Nginx : Web Server Performance Deathmatch http://joeandmotorboat.com/2008/02/28/apache-vs-nginx-web-server-performance-deathmatch/

9. image server

10. simple ex. 1 + Just use S3 - we can host website on Amazon Simple Storage Service doc : http://docs.amazonwebservices.com/AmazonS3/latest/dev/WebsiteHosting.html movie : http://awsdocvideos.s3.amazonaws.com/S3/HostingWebsites/S3_Hosting_Website.html

11. simple ex. 2 + CloudFront in front of S3 or web server - speeds up distribution of your web content doc : http://docs.amazonwebservices.com/AmazonCloudFront/latest/DeveloperGuide/Introduction.html CloudFront or or EC2

12. but + suppose - I (you?) don’t know, which size of images are suit for the target web page… - so many devices, so many display size, so many design changes, do we have to prepare so many types of image continuously ??? more useful system is needed. : dynamically respond requested image without any upload operation

13. so . . . http://6109.hidepiy.com/255/image-server-with-aws-nginx

Hinweis der Redaktion

Nginx is noted to be a good server for sites that need fast, efficient reverse proxies or serving of static content because Nginx is event-based it doesn't need to spawn new processes or threads for each request, so its memory usage is very low http://www.wikivs.com/wiki/Apache_vs_nginx
