With AWS, you can build a highly available ecommerce site that offers flexible product catalogs and business extensions. Maintaining a large product catalog and global customer base for an ecommerce site is challenging. The catalog is searchable, as well as individual product pages that should contain a rich set of information, examples like PDF manuals, and customer reviews.customers want to quickly find the product they're interested in and want the

I believe that you have been impatient with the word cloud computing. All kinds of concepts or gimmicks are overwhelming. But are these just gimmicks? If you attended the Autodesk developer day at the end of last year, I believe you will also remember the term cloud computing, but you may still feel that this is still far away from you, just like the cloud on the horizon, not reachable. However, cloud computing has come to us now! If you are still watching, I will introduce a Japanese customer w

What can cloud technology do? Speaking of what we need for half a day, today we are playing with the implementation of building PPTP services through Amazon AWS EC2 to scientifically access the internet. I have previously introduced the AIM (Autodesk Infrastructure Modeler). There are many cool AIM case videos on youtube, video tutorials, and so on. I would like to introduce them to you very much, unfortunately, most children's shoes cannot be accesse

Recently, the project needs to use the AWS S3 API to implement file upload and download function, only to find that the internet about. NET implementation of this feature is not many articles, there are a few are also very old version of the use of AWS description, writing and packaging classes, etc. are basically scrapped. Although this, but still very grateful that several articles gave me direction. I'll

AWS-based media Sharing System Architecture Media sharing is one of the most popular markets on the Internet. Customers have a strong desire to put photos and videos on their social networking websites and share their media content in custom online albums. The increasing popularity of media sharing means that website owners are facing increasing storage and bandwidth needs, accelerating the market commercialization, and providing faster performance th

Windows systems of foreign hosts generally support Chinese characters. If you do not have an AWS host, you need to install it on your own. The access speed of AWS hosts in China is also slow. Hope you can hurry up later. starting from the topic, AWS hosts can mount one more hard disk. We only need to mount the system installation disk. the process is as follows:

This section looks at how to use PowerShell to create CloudFront distributions inside AWS. CloudFront is an AWS-provided CDN service that allows you to create a distribution point that points to S3 or Web server, where DNS is automatically resolved to the nearest edge server for optimal access speed.The specific image interface operation can refer tohttp://beanxyz.blog.51cto.com/5570417/1532813Let's see how

The beans continue to see how PowerShell manages the AWS Virtual network VPC.I did not find a quick-start document on the Web, and the related commands came mainly from official API documents and Get-command searches.Http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_Route_Tables.html#route-tables-api-cliThe Configuration Wizard for VPC gives the configuration of 4 scenarios by default, and I'll configure it with PowerShell for the first simple

This section describes how to export data from one or more dynamodb tables to S3 buckets. Before you perform the export, you need to create S3 buckets in advance.NoteIf you haven't used AWS Data Pipeline before, you'll need to create two IAM roles before executing the process below. For more information, please visit creating IAM Roles for AWS Data Pipeline.export data from Dynamodb to S3 Log in to the

Label:Recently deployed a set of Web projects on AWS based on the Spring MVC 4.0 framework. The problem is that the local development connection to MySQL MongoDB is not a problem, only deployed to AWS (after a separate installation of the Web server) program is not connected to the MySQL server. The solution is as follows: 1. Set the JDBC connection as follows: jdbc:mysql://whatever_publichost_your_db_has.r

Lambda expressions implement finite state machines and lambda expressions There are multiple modes to implement the state machine. The most flexible and powerful method is to migrate tables. One of the disadvantages of this method is that you need to write a large number of small pieces of code to support the migration table. In C #3.0, it can be implemented in a very elegant way.In addition to finite state

Anonymous delegate and Lambda expressions, anonymous lambda expressions By using anonymous delegation (anonymous method), programming becomes more flexible. For Delegation and anonymous delegation, see my previous Blog "delegation and anonymous delegation". The Code is as follows: static void Main(string[] args){ Worker.TwoNumberHandleMethodDelegate method = delegate(int a, int b) {

[Java 8] Lambda expressions optimize recursion (I) and lambda expressionsRecursive Optimization Many algorithms rely on recursion, such as Divide-and-Conquer ). However, StackOverflowError often occurs when a common recursive algorithm is used to deal with large-scale problems. To solve this problem, we can use a technology called Tail-Call Optimization to optimize recursion. At the same time, you can save

The difference between a lambda expression and an anonymous method So why is a lambda expression shorter than an anonymous method? Does this kind of magic trick really work? Are there any important information missing? To answer these questions, let's compare the anonymous method with the lambda expression to see how the lam
