Other problems Recently, the company wants to migrate its architecture to the cloud, store it in S3, and use EC2 for servers. To make our architecture horizontally scalable, we use AWS Load Balancing for load balancing. In short, Server Load balancer refers to distributing a large number of client acc

offers more than 700 free and premium software products that can be run in the AWS free tier. If you qualify for the AWS free tier, you can use these products for up to 750 hours per month in an Amazon EC2 T2.micro instance without paying an additional fee (up to 12 months) for Amazon EC2 instances. Charges for the fee software are still applicable. Free software Fee Software Infrastructu

third-party library, we had to reboot the JVM to keep it working, and sometimes we had to get up in the middle of the night to deal with the problem. Resource utilization: We find that the CPU usage on rest servers is only 2-5%, which is a waste of resources, and Amazon EC2 servers are not cheap. Latency issues: The rest server is running on a different server. This creates a delay problem because, for each client request, it deserializes the

This is the second article in the series. In the first article, I used MySQL's built-in SSL support for stress testing, which produced some surprising results. Of course, it is expected that the throughput performance of queries using SSL is lower than that of queries without SSL, But I am surprised that the main performance bottleneck is the time spent establishing connections. This result naturally leads to further research. In particular, I want to make one-time comparison between MySQL's bui

Add/Remove in the menu) and any newly established Package Manager Synaptic Package Manager required when a conflict occurs ). According to Ubuntu, it has many ways to manage software. Ubuntu developers recently wrote on the Development wiki: "This type of repetition increases the number of interfaces that people need to learn, wastes space on Ubuntu CDs, and disconnec

see the wood for the trees, even when her head is in the clouds. ubuntu aims to keep free software at the forefront of cloud computing by embracing the API's of Amazon EC2, and making it easy for anybody to setup their own cloud using entirely open tools. we're currently in beta with official Ubuntu base AMI's for use on Amazon EC2. During the Karmic cycle we want to make It easy to deploy applications int

conducive to sustainable development. Today, the normal SaaS application is changed many times a day, which is very difficult for the monolithic application model. In addition, the impact of this change is not well understood, so we have to do a lot of manual testing. Then, the ongoing deployment can be tough.Monolithic applications can be very difficult to extend when resource conflicts occur in different modules. For example, a module that completes a CPU-sensitive logic should be deployed in

the architecture diagram for this pattern:The client makes a request to a service through a load balancer, and the load balancer makes a request to the service registry to forward each request to the available service instance. As with client discovery, the service instance is registered or unregistered in the service registry.AWS Elastic Load Balancer (ELB) is an example of a server-side discovery router that is typically used to equalize traffic from the Internet, or to use ELB to equalize tr

In traditional non-immutable publishing scenarios, all older versions of the software have been replaced.The implementation of the immutable deployment method in our current service still has a little deficiency. Because all environments are built on demand, the build time depends on certain factors, such as the time to start a new EC2 instance, and

There are many solutions, but the Libevent library and the Libev library can greatly improve performance and event handling capabilities. In this article, we discuss the basic structures and methods used to use and deploy these solutions in UNIX® applications. Both Libev and libevent can be used in high-performance applications, including applications deployed in IBM Cloud or Amazon EC2 environments that need to support a large number of concurrent cl

of Java, Eclipse is undoubtedly the leader in IDE. IntelliJ IDEA and NetBeans can only live in the halo of Eclipse. I don't need to talk about the power of Eclipse, but IntelliJ IDEA is actually a very good IDE, especially in its intelligence. Its Clone product ReSharper for. Net has been accepted by more and more C # developers. IntelliJ IDEA provides a large number of intelligent rules to help developers, such as code completion, usage conversion, format prompts, etc. When you get used to it,

Which of the following is more efficient when SQL Server's Insert operations are performed on heap tables or clustered index tables? Why is it high? Some colleagues have asked me this question before. To ensure the record efficiency of the logstore, I did a simple test. First of all, I should emphasize the following concepts: heap table: for a table without clustered indexes, the IAM page and PFS page are used to determine which page has free space.

used to obtain statistics. mode is sysname. Valid inputs is DEFAULT, NULL, LIMITED, SAMPLED, or detailed. The default (NULL) is LIMITED. 2.2 Scanning ModesThe mode parameter indicate the verbosity of the scan mode and return information. During the scanning process, the IS table lock needs to be requested on the scanned object.Limited Mode does not scan data pages, and for index, scans the leaf level for parent-level pages, and for heap, scans the IAM
