Improve Linux kernel and adapt scalability to the enterprise environment-general Linux technology-Linux programming and kernel information. The following is a detailed description. The first step to improve Linux performance is to quantify it. But how can we precisely quantify the performance of Linux or its equivalent system performance? In this article, members of the IBM Linux technology center described several benchmark program tests they perform
Many programmers spend a lot of time tuning application-level performance bottlenecks as they address JVM performance issues, and when you finish reading this series you will find that I might look at this kind of problem more systematically. I've said that the JVM's own technology limits the scalability of Java enterprise-class applications. First, let's start by listing some of the leading factors.

Overview
The following diagram is an overview of the project we are going to build. We're going to start writing the first microservices and we'll do a little bit of everything in this picture.

MicroServices do not exist alone, in order to better implement the micro-service architecture, the need to integrate many components mix-and-match use, can open the two-channel, invincible. Many danale o

We should be able to understand the performance of the system from the perspective of a real user, including testing the user experience from an external network and the number of calls to each component of the internal system, and the time of each call, and so on.

many people send me e-mail, these months I have received more than 50, some asked me when the next post, some thanks to me, some encouraged me, which is really helpful to me to complete this series of articles. So I would like to thank the people who emailed me, at the same time I am also very sorry that some of the mail I reply is not too timely. I would like to thank Asim, who often takes the time to answer some of my simple questions about MicroServices

Use the SingleCall server-side activation object to improve scalability.
Use singleton where you need to access a synchronized resource.
Use the singleton activation mode when you need to access a synchronized resource (Singletion is to say that no matter how many times the request server is an object executing the call).
Use singleton where you need the to control lifetime of server objec
Studio "Orcas" is released. This information can also be found in the common language runtime (CLR) add-in team blog.
In this series of columns, we'll introduce you to the development lifecycle of adding extensibility to applications and gradually versioning them over time. This month's column will cover the challenges that developers face when adding scalability to their applications for the first time, and how the API simplifies their work. Next m
In terms of creating, communicating, accessing content, sharing information, and buying products, the rapid expansion of a new generation of internet-based services, such as e-mail, blogs, social media, search, and E-commerce, has actually redefined the behavior and trends of WEB users. As the number of these systems continues to grow, IT professionals are witnessing the scaling up of data and data consumed, and growing scalability requirements and ne
successfully.
"Best Practices" is far from enough
While we were designing the system with the best practice documentation from many vendors, using stateless request processing logic, tiering, tiered deployments, separating OLTP and OLAP servers, no one ever told us that the system was going to deal with different types of scalability issues. In 2003, we designed key components related to system efficiency. In 2004, we stood the test of load and str

Part VII: Go microservices-service discovery and load balancing
This section deals with two basic parts of a robust microservices architecture-service discovery and load balancing-as well as how they facilitate the horizontal scaling of important non-functional requirements in 2017.
Brief introduction
Load Balancing is a well-
What exactly is the relationship between SOA and microservices?To tell you the truth, I really don't understand the fundamental difference between SOA and microservices, both of which are ultimately an architectural design approach to providing interfaces externally. I think the micro-service is actually with the development of the Internet, complex platform, business, resulting in the SOA architecture to a

With the introduction of several core components from the previous spring cloud, we have been able to build a short (imperfect) microservices architecture. As shown in the following example:We implemented service registries and service registration and discovery using the Eureka in spring cloud Netflix, while service consumption and balanced workloads across the ribbon or feign through the spring cloud Config enables the application of multi-environme

1. Several issues restricting BGP scalability
BGP is an IP network protocol currently used on the Internet. It provides stable and secure routing protocols for intercommunication between operators and provides a wide range of routing control mechanisms. To better control routing policies, most carriers deploy BGP to backbone routers. As the network expands, the number of routers increases, and the number of route information entries increases, it bec
