SSD refers to a special type of hard disk in which data is stored using flash memory. This makes SSD different from conventional hard disks, which rely on magnetic storage.
Alibaba Cloud offers easy-to-use high-performance virtual SSD cloud server, and now you can get a good deal to start. SSD cloud servers with data transfer plan just starting from $2.50 a month, come and join now!
The main advantage of SSD is speed. While SSD data transfer rates vary depending on which specific SSD devices you use and how your software accesses them, you can generally expect I/O rates to be about 20 times faster with SSD than they are on traditional hard disks, while overall data transfer rates are between 8 and 16 times faster.
SSD has been a popular solution for about a decade for personal computers, where SSD devices offer the additional advantage of being more resistant to physical damage. However, SSD is also an increasingly popular storage option for cloud-based applications.
But for an application, it is not only the speed that matters. So maybe you can try to combine SSD with Microservices which can provide more modularity and flexibility for your application as a whole. When you use microservices and SSD together in the cloud, you can multiply the benefits of each.
The main reason is that a microservices architecture allows you to choose specific components of an application to run with SSD storage. Rather than having to deploy the entire application on SSD (as you would if you did not have a microservices architecture), you can take advantage of SSD for the specific services that will benefit from it the most. The rest can run with standard storage, or no storage at all, depending on their needs.
The microservices that handle the storage for your application are often the most obvious candidates for an SSD hosting solution, particularly if your application will benefit significantly from faster throughput. For example, this could be the case for a web server with a heavy traffic load that needs to avoid bottlenecking at the storage level.
In other cases, you may not want to run your main storage service on SSD, but still take advantage of SSD for other specific parts of the application. For instance, you might host the microservice and database that handle authentication on an SSD-enabled cloud instance. This approach would improve the speed of logins for your users.
As a third example, your application might include a caching microservice. One way to enable fast access for this data is to store it in memory. But in some cases, such as those where you need to cache a large amount of data, it could be more cost-effective or scalable to use SSD storage for the caching instead. SSD is not as fast as in-memory data storage, of course, but for caching application or user data, it is likely sufficient.

If you already know that your server can potentially serve more than one website, and if you want to make the most of your ECS instance, there are multiple solutions to handle different content in one single instance ECS:
The best (and more elegant) solution here is to use Name-based Virtual Hosting, as it helps you to use better naming for your sites.
A Dual-mode SSD (Solid State Drive), a storage device which supports both Open-Channel Mode and native NVMe mode, has been developed by the Alibaba Infrastructure Services team, and an optimal software/hardware integrated solution based on the Dual-mode SSD is currently being deployed to Alibaba's internal servers. It is expected this novel storage system will lead to a 75% reduction in read latency and enhance the overall storage performance of data centers by as many as five times.
"The increasing proliferation of AI and cloud computing has led to more sophisticated demands in data centers, while traditional storage systems face severe limitation in meeting such demands.In light of these challenges, Alibaba has pioneered the research and development of a new storage system, the Dual-mode SSD infrastructure. This underscores our commitment to driving the innovation and optimization of technology infrastructure in a new AI and cloud era," said Shu Li, Senior Staff Engineer at Alibaba Infrastructure Services.
"By creating and sharing the Dual-mode SSD specification, we are also working with different manufacturers on related firmware and hardware products, leading to the fast development of SSD-centered infrastructure and ecosystems."
This topic describes the performance, metrics, and test methods of block storage devices such as disks (including Enhanced SSD, Standard SSD, Ultra disk, Basic disk), shared block storage (including Shared SSD block storage, Shared ultra block storage), and local disks.
This topic explains the mapping between the AWS products and services and Alibaba Cloud products and services used for a Web hosting scenario, and lists the strategy and tools required for the migration process.
An online computing service that offers elastic and secure virtual cloud servers to cater all your cloud hosting needs, with Intel Xeon E5-2682 v4CPU (Broadwell) processor, local SSD cloud disk capable of 240,000 IOPS and maximum PPS throughput of 7 million PPS.
A virtual private cloud service that provides an isolated cloud network to operate resources in a secure environment.
VPC helps you build an isolated network environment based on Alibaba Cloud including customizing the IP address range, network segment, route table, and gateway. In addition, you can connect VPC and a traditional IDC through a leased line, VPN, or GRE to provide hybrid cloud services.
