To help developers in Indonesia learn and use Alibaba Cloud services, Alibaba Cloud and CodePolitan launched DevHandal campaigns in September 2023. Among the over 10000 participants, many developers have documented their process of using Alibaba Cloud service with blog posts. This article from Hendry Wijaya is selected as the Top 10 Blog in the campaign.


Data is everything because most technologies are used to access, manage, process, and store data.

Furthermore, the requirement to manage data expansion becomes more critical, however running the complex algorithm in local machine is risky due to memory and computing limitations. People started leveraging the cloud’s power to run complex algorithms to complement these limitations, by doing cloud computing as long it flight on the market and help business thrives and scale up to perform better.

Cloud computing takes a critical role in companies that don’t have enough server capacity, but rent a server to be data centers from other companies as the vendor.

So that the company can reduce the cost of server maintenance because the vendor of the cloud server has many numbers of servers from other companies that subscribe to the cloud service. Everything that’s Cloud-related is currently making a major disruption in the world of technology, which enlarges the migrations until focussing all on the cloud and already changes a lot of things that make the company more valuable in storing the data. Cloud Computing changes the fundamentals of Information technology, in which the physical storage of data is not necessary because it can manage and process data virtually in the cloud.

This is the reason why Cloud Computing is Urgently Important to every data department in most company, not even to small business because the data drive help grow and scale up the business. And this article explains the experience belajar cloud yang diselenggarakan oleh Alibaba Cloud and Code Politan.

Certification Cloud Opportunity by Dev Handal

Everybody reads this page has a jackpot that Developer Handal recently released the program that named devhandal which is a coding courses scholarship so everybody has the opportunity to learn coding in 1 year for free to achieve international developer certification. THIS IS YOUR OPPORTUNITY to learn Javascript and Master your coding skills with Javascript from DevHandal held by CODEPOLITAN which collaborates with ALIBABA CLOUD. While the Codepolitan referred from CodePolitan Website, CodePolitan is an online learning platform for programming that uses the Indonesian language and was developed specifically to help young students and professionals learn programming to become competitive digital talent in the era of Industry Revolution 4.0. On the other hand, Alibaba Cloud referred to the Alibaba Cloud Website, which is a cloud computing company and a subsidiary of Alibaba Group. Alibaba Cloud provides cloud computing services for digital businesses and the electronic commerce ecosystem.


Before we continue, let you know that learning Fullstack Javascript is worth for data people because learning Fullstack can help you understand to make app which the machine learning model is embedded in, so you have an understanding of how to deploy the machine learning model as production into the real world app and turn the model as the piece of program or features in the applications either it’s mobile app or web app. Most highlighted javascript use in data science is on visualisasi data, that javascript is known for website development with aesthetic interface, by using javascript make the display of visualization more interesting. So Javascript can be used to make complex data visualization by the Object-oriented programming language essential for developing online graphics and visualization and can be worked with the product team. Javascript’s Libraries used for data visualization are Chart JS and D3 JS

On the machine learning model, Javascript can be used to develop a Machine Learning Model with Automation. Likewise on operating tensorflow that’s the open-source library that can be implemented using javascript to execute the Machine Learning Model, Like Tensorflow JS that can build a Machine Learning model on Web Applications.

In addition, data scientists can use the library to develop Applications and Automation Tasks. Data scientists that leveraged in web development can be able to develop websites or applications that combine technology and data, having some knowledge and ability of the process of platform development can be useful when collaborating with the development team or developing their own product. Javascript also can be used to make a professional portfolio that contains data visualization and the model as the online presence to be displayed for employers or recruiters.

Leveraging data science with full stack development skills also upskilling on managing data pipeline from capture, database, analysis until presentation. It is also worth being a data scientist that is attached to web development skills as those 2 fields is broad and have much stuff to be learned in a lifetime. Those are the benefits when data people like data science or data analysts leverage javascript, especially expanding data visualization skills on web app. After that let’s get back to the topic of the learning experience of a certified developer with Alibaba Cloud.
