BaaS, now there are two meanings translation of a backend as a Service (Backend as a Service), one is the blockchain as a Service (blockchain as a service Blockchain as a Service). In essence, it is one thing, just the name used in different scenes, explained one by one.
What is BaaS?
BaaS (Backend as a Service) is a new type of cloud service designed to provide back-end cloud services for mobile and web applications, including cloud data/file storage, account management, messaging, social media integration and more. BaaS is a vertical cloud service. As the mobile Internet continues to be hot, BaaS is also favored by more and more developers.
It can be said that BaaS was born on the mobile Internet, and developed to accelerate the development of mobile applications and reduce costs. BaaS can bring the service of back-end capabilities. Serviceization also brings the possibility of back-end capability optimization management. These capabilities are born by service developers, and repeated construction and planning will be avoided at an early stage. By using these services to realize their own business functions, developers will further request the capabilities of the services and promote the development of back-end services.
What is the blockchain baas?
BaaS (blockchain as a service); blockchain service refers to the data generated by the blockchain, providing blockchain-based search query, task submission, and a series of operational services. At present, in the blockchain field, only block browsers of major public chains can be called blockchain services, and some public chain derivative applications: deposit type-Factom, digital identity-uPort.
These applications all have a feature, based on the existing public chain, play and strengthen the existing functions of the public chain, so that the public chain provides better blockchain services for everyone. In other words, if you want to develop a blockchain service application, we generally mean to develop an application on the public chain. Blockchain-as-a-service BaaS is mainly a concept proposed by Microsoft and IBM. It is a new type of cloud service, a cloud service that combines blockchain technology . For example, Microsoft’s Azure cloud computing platform and IBM’s Bluemix Garage cloud platform provide blockchain as a service BaaS.
BaaS This kind of server is bound to be a trend in the future. Let’s briefly explain the reasons:
1, the back-end business is easier to abstract: for example, the business is a piece of data, a RESTful API, but also compatible with multi-end (Web, iOS, Android, etc.). This kind of abstraction itself requires each family to make a service similar to BaaS, such as Facebook, Google, etc. The internal and external interfaces are basically API-based and SDK-based.
2, the back-end technology itself is not in the business logic, mainly performance and stability. Anyone who writes simple business logic is the so-called “full stack engineer”, but how to guarantee performance in the case of large-scale data and how to guarantee the load in the case of a large number of requests is the key to the back-end technology. These things, the service itself is better centralized operation and maintenance.
3, BaaS does make the writing process more simple, once a simple thing, it will produce more and more users, similar to the front-end jQuery, in fact, jQuery is a simple library, the same time YUI framework The system can do more things, but it is not simple enough, and simplicity will become a trend;
The overall cost is lower. All developments take into account cost issues, which is why cloud services such as AWS can arise, saving costs and saving operations. And the BaaS service like LeanCloud is a product on the upper level of this service, which saves your cost and saves server development.
In summary, basically it can be confirmed that it will be a trend in a period.
Blockchain as a Service BaaS is a space for companies such as Microsoft and IBM to create a space from their own cloud service network to run a blockchain node. Compared with common nodes and exchange nodes, the main purpose of BaaS nodes is to quickly establish their own development environment, provide a series of operation services based on blockchain search query, transaction submission, data analysis, etc. It is centralized or decentralized to help developers validate their concepts and models faster. The serviceability of BaaS nodes is: more instrumental, easy to create, deploy, run and monitor blockchain.
Development of BaaS
We are familiar with IaaS, PaaS and SaaS. These are also the stages of cloud computing development.
IaaS, Infrastructure as a Service: Infrastructure service, born AWS, Alibaba Cloud, etc.
PaaS, Platform as a Service: Service platform development , the birth of Google APP Engine, Alibaba Cloud, Baidu open platform, Tencent development platform, sina development platform.
SaaS, Software as a Service, software service, such as Microsoft Office 365.
BaaS, Backend as a Service, back-end service.
BaaS is between PaaS and SaaS. In order to meet the needs of the rapid development of mobile Internet, the back-end capabilities are provided in the form of services. Based on the development capabilities of the PaaS platform, SaaS is used to serve the back-end capabilities. Developers develop their own Software solutions based on this.
BaaS is further development of PaaS
BaaS is also a replacement (or alternative) for mobile middleware, which uses a unified API and SDK to connect mobile applications to back-end cloud storage. Traditional mobile middleware integrates back-end services into applications through local physical services. in. And BaaS integrates back-end services through the cloud. The biggest difference between middleware and BaaS is whether they contain or provide cloud services. BaaS can be said to be an extension of the PaaS platform in the mobile vertical field, or more, the fusion of mobile middleware and cloud.
BaaS simplifies the application development process, while PaaS simplifies the application deployment process. PaaS is a development platform for executing code and managing the application runtime environment. Users interact with the platform through code version management tools such as SVN or Git. For developers, PaaS is like a container, and the input is code and configuration files. The output is a URL that can access the app. The BaaS platform further abstracts user requirements, such as user management. After the developer wants to create a user database table (model), the client can directly manipulate the corresponding model through the Restful interface, and all operations can be abstracted into CRUD. Previously, developers needed to create tables, write interfaces, and write validation. In the BaaS platform, developers only need to define the model, and the platform will automatically generate the corresponding interface, which allows developers to focus on specific client code.
BaaS is an upgrade of the development architecture, entering the era of cloud computing services from the era of J2EE middleware
J2EE Stack -> BaaS
Since the rise of the web era (web 1.0, web 2.0), we have entered the J2EE era until now. My development architecture is basically covered by various J2EE specifications. J2EE defines a set of services (services) and application interfaces. (APIs) and protocols provide technical stack support for developing web-based multi-tier applications:
1. JDBC (Java Database Connectivity), the JDBC API provides a uniform path for accessing different databases
. 2. JNDI (Java Name and Directory Interface) Remote method request, RMI protocol calls the method on the remote object. It uses serialization to transfer data between the client and the server.
3. Java Servlet, web server function extension
4. JMS, object-oriented message middleware Intercommunication application interface
Our server-side development has thus entered the middleware era, leveraging the capabilities and specifications provided by these middleware to meet business needs. J2EE, the development of middleware has finally formed the foundation of PaaS in the era of cloud architecture. These middlewares, servers, etc. form a development platform, using various specifications and protocols to provide developers with comprehensive capabilities,
which is what we are most familiar with and accustomed to. Development architecture. We would once think that the function is too powerful and rich, and it has developed to be good enough. The rest is that developers need to work hard to master various technical details. When we have this kind of thinking, it actually means that this structure has developed into a bottleneck period.
Under the pursuit of our team’s development efficiency and cost, this kind of development architecture has gradually exposed the shortcomings of teaching. He has higher requirements for the technical quality of developers and set a certain barrier to the improvement of development efficiency. When we want to further investigate development efficiency and reduce development costs, we need to further develop and upgrade this development architecture. At the same time, with the advent of the cloud computing era, it also provides a basis for the development of technical architecture upgrades.
How BaaS can improve development efficiency and reduce development costs
Let’s think about what we need to do to develop a typical web business system.
This kind of development is generally divided into back-end development and front-end development, in which the back-end needs to be responsible for data storage, retrieval, integration, business logic, authentication and authorization, etc., and the imagination can be very simple:
In fact, this is closer to the truth:
However, these are not all:
To be an Internet high-reliability, high-performance, high-performance web system, the ability to develop may take a long time to accumulate and pay huge resource costs.
When more and more similar systems are developed, we will feel that we are doing a lot of similar work in addition to the specific business logic. If there is an interface for us, let us choose to input the function we want to output the final API with one click, the world will be much better.
The development of cloud computing has made it possible for us to make this idea possible.
We input the number of servers and configurations we need on IaaS such as Alibaba Cloud. After clicking, we will solve the server deployment.
When we choose RDS, OSS, and messaging as the middleware service on Alibaba Cloud’s PaaS, we need the storage, messaging and other capabilities to be solved with one click.
So further hope that many of our shared services, such as authentication and authorization, message push, data modeling, maps, voice, etc., can also be solved with one click, and the functions provided by Alibaba Cloud can not reach this stage.
The way to provide these services is BaaS, the back-end is the service. The ability to package the backend is provided as a service.
Form a platform for back-end capabilities and build a new development architecture:
This is the formula for the BaaS architecture:
BaaS = IaaS + PaaS + APIs + SDKs
Back-end capabilities are delivered as services using IaaS, PaaS, API, and SDK foundations.
For developers, you only need to use the API or SDK to complete the corresponding functions, so you can focus on the development of your own business logic. Under this development framework, the development of business systems will be greatly accelerated. Without the complicated development and maintenance of the back-end, it is only necessary to use the future services to complete the development of business logic. The technical requirements for developers are also greatly reduced.
BaaS industry ecology
BaaS has been growing rapidly in the industry since 2012. In April 2013, Facebook acquired Parse; in June 2014, Apple released CloudKit at the annual WWDC; by October 2014, Google also acquired Firebase.
Parse, Firebase, etc. are among the best in BaaS startups. The actions of the three major Internet companies in BaaS in the last two years also reflect their emphasis on BaaS.
Facebook expects to end the state of information silos between applications, allowing content between different applications to interoperate and seamlessly jump, so it has released a “protocol” called AppLinks, but behind this protocol requires a backend service like Parse Provide a series of technical support such as data storage, computing power, and Push notification.
For Apple, CloudKit provides a robust and resilient back-end solution that helps developers reduce the need to write server code and maintain servers. Obviously, Apple’s move is also to reduce the cost of developing iOS applications and maintain the prosperity of the iOS ecosystem.
Firebase founder James Tamplin said on the blog, Firebase and Google Cloud Platform can complement each other very well. And after Apple provided CloudKit for iOS developers, Google may also want to have similar services to facilitate the developers of the Android ecosystem.
The value of BaaS
BaaS can solve the gap between technology and business. Through BaaS, the business development team is like an outside startup. Their core competitiveness is the understanding and realization of the business, so that they can quickly and cost-effectively. Make applications that meet your needs, and then invest the main resources into expanding your core competencies.
The BaaS platform itself can be built as a product, sublimating the capabilities of PaaS into BaaS services that are easier for developers to use. The platform is independently operated and deployed, and provides high-performance, high-performance and high-reliability service capabilities.
The BaaS platform can be used as a cloud product for small and medium-sized developers, startup teams, companies and organizations to provide a variety of BaaS related products and services.
The threshold for personal mobile developers to achieve creativity. For individual mobile developers, it is necessary to combine the front-end and back-end development capabilities to achieve good ideas. This requires outsourcing or forming a small team, which is not easy for most people.
The cost control and rapid development needs of the startup team. For the entrepreneurial team, rapid agility can seize the market opportunity, and the back-end development and operation and maintenance of mobile applications are repeated and monotonous, which will take a lot of time and manpower. For various reasons, the entrepreneurial team often has multiple roles and manpower. Insufficient, resulting in the continuous extension of product launch time, many good ideas have died like this.
Enterprise data security and agile development needs. For enterprises, they have to create their own backgrounds, and they are hurting their lives. Instead of investing manpower and time in repeated meaningless labor, it is better to buy existing mature services and invest their human resources in more creative positions, but each company Business logic is also very different, so there is a need for private cloud customization services that adapt to the needs of your business.
Simply put, Baas is the provider of back-end business logic solutions for business development. Provide free public cloud services for individual developers and entrepreneurial teams, and provide private cloud customization services for enterprises. BaaS’s main idea is to eliminate the hassle of back-end development and deployment for developers, so that developers do not need to purchase a server (IaaS), no need to deploy a back-end environment (PaaS), no need to write back-end code (BaaS), and easily modify business logic ( SDK and API) to quickly implement ideas (Happy).
At the same time, these unnecessary backs mean various cost reductions, you don’t have to worry about operation and maintenance, you don’t have to learn various middleware, don’t worry about high concurrency stability, etc… All of this becomes A simple service.
As the basic service of the mobile Internet Baas is open to all web and mobile applications, and the mobile Internet is huge.
Great value with the enterprise market. BaaS connects cloud services with developer services, free for individuals, and charges for large and medium-sized business users.
Linked to big data, mastering the future with one hand BaaS is characterized by sharing users with developers and collecting user behavior data through APIs and SDKs. Combining the business intelligence of big data will generate huge value and data barriers.
