ecs vs ec2

ArticleDirectory 1. Where can I find the load balancing configuration page? 2. port forwarding Configuration 3. Health Check 4. 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

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

possible to discover exceptions in a new publication only after the publication has completely ended. 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

infrastructure. The advantage of the cloud over the hosting company is its resilience, and the cloud can adapt quickly as the application rapidly increases demand. Cloud service Provider With Amazon EC2, you can install everything you want in a virtual machine. EC2 offers a lot, but you still need to install the operating system, Web server, network or application container, database, and everything you

Due to poor filtering of ecshop, tens of thousands of online stores can be getshell (certain conditions are required) I tested both v2.7.3 and v2.7.4 successfully.

You can define the price range (for example, 1-30, 31-200,201-, 1001-, or more) in the ecshop background. The front-end is automatically reflected in one way, and the price range of each category can be set at will, make the price range more humane. 1. First, modify the database structure of ecshop to add a new field to ecs_category, Log on to the background, select database management> SQL query, and run the following SQL statement.
