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

Description of the pattern/solution in the cloud: Some terminology explains or how to solve some problems in the cloud, why a pattern or description configuration can become a pattern. Implementation: A description of how to use AWS to implement a pattern.

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

Firewalls are the core and increasingly complex part of network security, and are constantly fighting against the ever-changing threats faced by enterprises. The updated firewall can analyze network traffic behavior, protocols, and application layer data. However, when resources are transferred to Amazon cloud, enterprises may find that there are no firewalls of the same quantity and type available. In this article, we will investigate the built-in firewalls, third-party firewalls, and open-sour

quickly and easily deploy applications to EC2 instances. Accelerate deployment, control deployment cadence, reduce the complexity of application upgrade updates, and reduce the errors and risks of manual deployment operations by standardizing and automating deployment processes. This ultimately allows users to quickly release new features while ensuring the quality of the deployment and avoid disruption of service during deployment. On a support scal

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

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

Ubuntu uses Amazon EC2's APIs to place Free software on the cloud computing front, so that anyone can use completely open tools and easily set up their own cloud.

After careful research and comparison of multiple cloud service platforms, Shanghai Longyou finally chose to use the AWS cloud platform service, the overall architecture is improved by using cloud services such as EC2, VPC, RDS, S3, cloudfront, and route53 of AWS. When choosing AWS, the Shanghai tour is mainly based on the following considera

With 10gen, you can use Python andJavaScript and RubyUse programming languages to develop applications. The Platform also uses the sandbox concept to isolate applications and uses many compute

Amazon announced that they will provide new customers with a one-year free AWS usage method starting from November 1. The products involved include EC2, Server Load balancer, EBS, and S3. The methods provided by SimpleDB, SQS, and SNS to new and old customers are not yet determined. Customers can use the service wherever they want, but there are the following restrictions: 613 hours for Amazon EC2
