What Is The Importance of Software Architect

Someone said, "Architecture is about anything important,  whatever it is."

But, what software architecture really is. Four components construct a foundation of software architecture.

 

Structure

It is more like an architectural style such as monolithic, microservices, layered, etc. So, if an architect talks about microservice, for example, he just talks about the software structure he is building.


Characteristic

It defines the success criteria of software such as reliability, scalability, security, availability, etc.

 

Decisions

It defines the rules on how the software is constructed. For example, a decision in a software development project states that each service in a microservice system can only have full-access permission to its own database. When a certain element cannot fully follow the rule then it is called variance in the system.

 

Principles

The difference between decision and principle is that principle is more about providing guidelines for the developers. For example, all communications among services in a microservice system must be asynchronous to improve performance, but developers can choose the communication standard that will be implemented.


Then, what should be done by a software architect? These are a few of the necessary works.


Make architectural decisions

It is different from technical decisions like choosing what framework should be used in the program. But, it rather defines the characteristics or capabilities that a framework should have. For example, a framework should have built-in support for communication through the MQTT protocol.


Continuously analyse the architecture and monitor the implementation of decisions

The system should be analysed continuously to find possible improvements. Besides, the architect should always be updated with current trends to help them define the roadmap of improvements. Implementation of any decisions in the development should be monitored to prevent unexpected issues made by developers who don't follow.


Diverse exposure and experiences

It is good for an architect to have knowledge of broader topics or be exposed to many kinds of technology and solutions in the market. Unlike developers who have to go deep, an architect should maintain technical breadth that helps make decisions in a project that includes diverse topics.

 

Have business domain knowledge

To make an architecture that solves problems and delivers value, an architect should understand how to gather the requirements, define the problem, and align with business needs.


Good interpersonal skills

To succeed in the implementation, the architect should have good communication with the developers so that they can understand the design and decisions well. Besides, anytime an architect makes a decision, some people in the company with limited knowledge about the foundation may start questioning the decision.

Deploying a Web Server on UpCloud using Terraform Modules

In my earlier post , I shared an example of deploying UpCloud infrastructure using Terraform from scratch. In this post, I want to share how to deploy the infrastructure using available Terraform modules to speed up the set-up process, especially for common use cases like preparing a web server. For instance, our need is to deploy a website with some conditions as follows. The website can be accessed through HTTPS. If the request is HTTP, it will be redirected to HTTPS. There are 2 domains, web1.yourdomain.com and web2.yourdomain.com . But, users should be redirected to "web2" if they are visiting "web1". There are 4 main modules that we need to set up the environment. Private network. It allows the load balancer to connect with the server and pass the traffic. Server. It is used to host the website. Load balancer. It includes backend and frontend configuration. Dynamic certificate. It is requ...

Installing VSCode Server Manually on Ubuntu

I've ever gotten stuck on updating the VSCode server on my remote server because of an unstable connection between my remote server and visualstudio.com that host the updated server source codes. The download and update process failed over and over so I couldn't remotely access my remote files through VSCode. The solution is by downloading the server source codes through a host with a stable connection which in my case I downloaded from a cloud VPS server. Then I transfer the downloaded source codes as a compressed file to my remote server through SCP. Once the file had been on my remote sever, I extracted them and align the configuration. The more detailed steps are as follows. First, we should get the commit ID of our current VSCode application by clicking on the About option on the Help menu. The commit ID is a hexadecimal number like  92da9481c0904c6adfe372c12da3b7748d74bdcb . Then we can download the compressed server source codes as a single file from the host. ...

Increase of Malicious Activities and Implementation of reCaptcha

In recent time, I've seen the increase of malicious activities such as login attempts or phishing emails to some accounts I manage. Let me list some of them and the actions taken. SSH Access Attempts This happened on a server that host a Gitlab server. Because of this case, I started to limit the incoming traffic to the server using internal and cloud firewall provided by the cloud provider. I limit the exposed ports, connected network interfaces, and allowed protocols. Phishing Attempts This typically happened through email and messaging platform such as Whatsapp and Facebook Page messaging. The malicious actors tried to share a suspicious link lured as invoice, support ticket, or something else. Malicious links shared Spammy Bot The actors leverage one of public endpoint on my website to send emails. Actually, the emails won't be forwarded anywhere except to my own email so this just full my inbox. This bot is quite active, but I'm still not sure what...

How To Discover Exposed Digital Assets for Free Using Noxtara

If you have a website or public-facing digital assets, you might wonder whether they’re secure and what potential entry points could be at risk. A great first step is to list all the digital assets connected to your main domain. One free tool that can help with this is called Noxtara. It offers a variety of security tools in one integrated dashboard, including a feature for discovering public-facing assets. Creating a free account is simple—just head over to the registration page . If you’ve got a company email that matches the domain you want to scan, it’s best to use that since it makes adding the domain to the Noxtara platform much easier. No worries if you don’t have a company email, though; you can still sign up without a problem. Just keep in mind that when you want to add your company’s domain for scanning, you’ll need to go through a quick DNS record check. Registration Once you’ve registered, you can set up a team and add your domain in the team settings. If the domai...

How To Verify Phone Number for Free Using WhatsApp

If you have a product or business that maintains user information like phone numbers, verifying the validity or ownership of the phone number could become important, as the phone number can be used as an authentication method or targeted marketing channel. The typical phone verification procedure is by generating a code or OTP in our application, sending that OTP to the user's phone, and then the user should insert the OTP in our application for verification. The OTP can be sent to the users through services like SMS or WhatsApp that require a valid phone number. For internet-based communication, WhatsApp has become the de facto standard for sending the OTP. WhatsApp requires its users to have a valid phone number during account creation, and it already has a huge number of users, approximately 3 billion in 2025. Using that common procedure, WhatsApp will charge us for each OTP sent. The cost depends on the country of the target phone number. For Indonesia...
