computing power.2. What does IaaS mean?Iaas:infrastructure-as-a-service (infrastructure as a service)The first layer is called IaaS, sometimes called Hardware-as-a-service.A few years ago if you want to run some business applications in your office or on your company's website, you need to buy servers or other high-level hardware to control your local applications and get your business up and running.But n

Explanation of the Checkpoint:For performance reasons, the database engine modifies the database pages in memory (buffer cache), but does not write these pages to disk after each change. Instead, the database engine periodically issues checkpoint commands for each database. Checkpoints writes modified pages in the current memory (called dirty pages) and transaction log information from memory to disk and logs information about the transaction log. The

Most relational databases have the advantage of performance by "not forcing modifications to the block at the time of submission" but rather "writing log files in the form of a record (in redo log)" when committing. That is, when a user commits a transaction, the write data file is "asynchronous" and the Write log file is "synchronous".This can cause the database instance to crash when the modified data in the Db_buffer in memory may not be written to the data block. When the database is reopene

Understanding Public Clouds: IaaS, PaaS, SaaS Contents Overview Infrastructure as a Service (IaaS) Platform as a Service (PaaS) Software as a Service (SaaS) Summary Overview Several months ago I wrote about the different types of Cloud computing in a post titled: The specified Flavors of Cloud Computing. in that post I described Software as a Service, Platform as a Service and I concluded with a descriptio

Cloud Service has now become a household name. If you do not know the differences between paas, IAAs, and SaaS, there is no difference, because many people do not know."Cloud" is actually a metaphor for the internet.

Every time I talk about SQL Server, I'll start by talking about what happens inside SQL Server when we execute the query. Executing a SELECT statement is straightforward, but executing DML statements is more complex because SQL Server modifies the related pages in memory and records the entire transaction in the transaction log.After describing these specific steps, I always ask the same question: Does SQL Server crash when we have an uncommitted transaction that happens to have a

There's a lot of information on the web that doesn't make it clear whether the log switch is a full checkpoint or an incremental checkpoint. Some say it's a complete checkpoint, and some say it's an increase. Quantity Check point. In fact, if you have a deep understanding of the difference between a full checkpoint an

alternative to providing users with low-cost data center scalability, IT infrastructure, software, and a variety of new applications, while guaranteeing quality of service.Seeing here, you may still ask, how does cloud computing provide infrastructure for us through the Internet? How do I develop software and products through Internet access to the cloud platform? How do I use cloud computing to run the core applications of my business?In fact, it is very simple, there are three main ways of la
