What is Salesforce?
AppExchange, career opportunities, innovativeness, etc.
Salesforce is a platform that's completely hosted on the cloud web server of the Salesforce Company. Salesforce Company was founded in 1999 by a former executive director of Oracle – Marc Benioff. The main idea of the platform is the building of available software and its full implementation into online mode as an internet service.
To be clear, Salesforce went beyond the usual CRM for a long time ago. Salesforce is a cloud platform, based on which a lot of interesting stuff is founded.
Salesforce allows us to create and deploy individual solutions, and automate business processes, integrate into external apps.
The majority of worldwide companies are clients of the Salesforce company and use this platform as a solution for their business needs. Among them are Adidas, AWS, Canon, Philips, Toyota, American Express, Western Union, Cisco, KLM and a lot of others. Recently, I discovered on my own that U.S. Visa Center uses Salesforce for visa request compilation, processing, and issuance.
Salesforce has a lot of various representatives in the IT-world, and for sure, they offer ready integration solutions, enhanced services for the satisfaction of end customers, and also many opportunities. Among them are Apple, Microsoft, Google, Amazon.

Benefits of work on Salesforce for developers

Easy to start

And it's one of the major advantages of Salesforce. You don't need to install any program, there aren't any requirements to your hardware. Accommodation on the cloud allows you access to data in real-time. It means that you can use the platform anytime and anywhere.
To work on Salesforce you only have to have access to the internet. All you need is to go to the website, login... profit!

Multitenant Platform

All users of Salesforce have a mutual infrastructure. It gives an opportunity for an automatic and simultaneous update for all the users of the platform. You receive the freshest and newest functions with automatic updates three times a year.

Training Organization

Everybody has an opportunity to create a free organization for studying, practicing or testing. It is a full-function development environment, which you can use to create your product – package that can be produced as an application for AppExchange.

AppExchange

AppExchange from Salesforce allows you to sell your products or receive access to thousands of useful, protected and certificated products or integrations, that are created by other users. For example, apex-lang is an open library of assistance classes written on Apex to get rid of the lack of the major classes of the platform. Rollup Helper package allows us to aggregate data by a certain set of Salesforce performance standards without using of Apex code.
Possibility of integrating to other systems

Salesforce gives a possibility for any integration. Besides, it proposes lots of embedded integration, for example with Heroku, Outlook, Gmail.
For example, you can have integration between Salesforce and .NET app for management and synchronization of client requests. Incoming calls are using REST web-service. Outgoing calls are using Apex callout – HTTP request from Apex code.

Easy to use and setup

The navigation panel is pretty intuitive. Each tab is separated from another according to a category. To get access to settings or custom developing you have to use the Setup menu. The menu is divided into different sections depending on the objective of using. For example, object setting up happens through the Object Manager. You can create, check or make changes in Apex classes through Platform Tools → Custom Code.

Career opportunities

Salesforce-specialist has an opportunity to grow up and move either towards the technical area or project management and consulting. There are very few good Salesforce specialists today, and each of them is very valuable. Statistics shows that the level of wages of Salesforce developer is higher than of .NET specialist, for example, if we are talking about the same experience.

Ready solutions

One of the main pluses of Salesforce that the majority of the functionality that's required by most of the products that are already implemented and tested. For example, built-in functionality Email-to-Case allows creating Case notes in the system automatically via e-mail. Or Web-to-Lead, that creates HTML form, that can be inserted to a web-site.

Innovativeness

Salesforce is constantly changing and developing. It gives new opportunities for examining and improving. The company has been active in regards to startups. There are in 2010 was bought a first of cloud platforms – Heroku, that allows to deploy, launch and manage applications written on different programming languages and frameworks.
During last year Salesforce actively integrates AI elements into the platform. The technology uses all data within the system: client data, chat messages, e-mail, calendar and e-commerce, data flow from social-medias, such as twits and photos to create maсhine learning models. One of AI examples on Salesforce is a functional Einstein Bots for Service Cloud that uses machine learning for better or faster client service. It allows sharing client requests to the bots that implement the connection of machine learning and user data processing for the next solutions.
Custom development on Salesforce

Regarding custom development, then Salesforce has sufficiently powerful instruments for this. Apex is its server language. This is a similar language to Java which supports the majority of possibilities to code in OOP style. But for example, a switch operator was added only a year ago.
Apex (like other OOP programming languages) supports classes, interfaces, collections, variables and constants, conditional operators (if-then-else), 'for' and 'while' are cycles. But, besides, Apex is being developed, preserved, compilated in the cloud. Also, it allows for completing direct database queries (SOQL and SOSL query). Apex may be implemented by triggers before or after certain DML operations. Besides, Apex is a case-insensitive language.

Usually, Apex is used for the implementation of complicated business processes, building web-services or e-mail services. Apex can be requested with the help of the triggers before or after changes in the database. There is a possibility to launch Apex classes at a certain time.

If we are talking about UI, there are two variants. First and oldest – Visualforce pages that support MVC pattern. Visualforce pages are developed in Classic Mode – first Salesforce interface that started its existence far away in 1999. Visualforce pages consist of 2 elements: Visualforce Markup and Visualforce controller (last isn't important). Visualforce Markup may have standard tags (Visualforce library has a big set of its tags) and also it supports any standard web-technology (CSS, JavaScript, HTML, Flash, etc.) Visualforce Controller may be standard and custom that's apex class with a set of variables and functions.

Conclusion

In summary, I would like to remind you that IDC analytics expect that Salesforce will create over 3 million workplaces in 2022. It makes Salesforce a high required and well-payed specialization in the IT-world.
