We need to ask at least these questions before starting to build our application, web, desktop, or API software. The first part of this is thinking about the first question.

Do I need to use a cache?

It depends on the database source, budget, and server. It depends on what kind of application and more. In most applications, it's not necessary to use a cache, actually, because maybe you need to use more resources to keep the cache than the database. But most news website needs to use a cache to keep them fast and simple to read. When it's not necessary, just check the database.

What did you think about using a cache in your application?

Maybe your application does not necessarily use a cache for the data. For my mobile app, I need to use local cache inside the device, and to do this, I need to create and use a local database or local files as a cache.

For a web application, maybe I need to use local cache with JavaScript.

For a desktop application, maybe I need to use a local cache with a small database like SQLite or local files. Many application uses it.

What kind of cache does your application need?

We have a local cache that we can use for files or a local database. If I decide to use a local database, please use a password. If I decide to use local files, I will encrypt the files and make sure that the data there is secure.

Do you know what kind of cache you can use in your application?

Local cache
- A local and separate cache per application.
Server cache
- An API cache gets the information from the database, saves it in memory, and returns it to the client.
Service cache
- Services inside the hosts that we need to pay to use the cache memory before checking the database.
- Caching is a technique used to store frequently accessed data in a faster, temporary storage location (the cache) to reduce the need to access slower, primary storage locations like databases or hard drives. This leads to significant performance improvements, especially in applications that handle a lot of data or have high traffic.
- Caching services store frequently accessed data in a faster storage location (like RAM) to reduce access times and improve application performance. This can involve various techniques like in-memory caching, content delivery networks (CDNs), and distributed caches. Popular caching services include Amazon ElastiCache, Redis, and Cloudflare's CDN

Types of Caching Services:

In-memory caching: Stores data in the computer's RAM, providing very fast access times. Examples include Redis and Memcached.

Content Delivery Networks (CDNs): Distribute content across multiple servers located closer to users, reducing latency and improving load times for websites and applications.

Distributed Caches: Spread the cache across multiple servers, offering scalability and high availability.

Server Cache

If my application is web, I would like to use cache, as I have it hosted on one server, I use one database and a backup of it every day; maybe I need to use a server cache, and for it, I created a .NET library to help me with it.

//instance
var main = new MemoryCacheLibrary.Main();

//custom class
var _user = new User
{
    Id = 1,
    Name = "Mauricio"
};

//set cache using custom class
main.SetCache<User>("tt", _user); 

//set cache using simple string 
main.SetCache("tta", "mauricio");

var result = main.GetCache<User>("tt");
Console.WriteLine(result);

The code shows how to use it, and you can use it for free here in this link https://mauriciojunior.net/Nugets. I will keep talking about cache and solutions for my application here. Feel free to reach out to me via my website www.mauriciojunior.net.
