A Virtual Office for Remote and Hybrid Workers

Today.ly is a virtual office service that provides all of the benefits of a physical office for professionals working from the comfort of their homes. Engaging Alternative for Remote Work The debate between working remotely and working in the office rages on. We won't get into the pros and cons of each work style. However, we believe that working remotely in Today.ly's office simulation can make remote work more fun and interactive (and potentially more attractive to die-hard in-office workers). Sure, the days of everyone being cooped up for months on end are over. For some companies and industries, working from home is no longer a necessity. Today.ly allows teams to work remotely without completely losing the serendipitous moments that physical offices provide.  Working Together as Partners SupremeTech started developing Today.ly after being approached by our current business partner in Singapore. They came to us with the idea of creating a virtual office space during the peak hours of remote work. Our partner relied on us to leverage our expertise in R&D to create and develop an MVP. One of the main reasons for choosing SupremeTech as their partner was the proximity of Vietnam to Singapore. However, they also recognized our ability to deliver a quality product quickly and efficiently.  Communication and Cross-border Collaboration As with most offshore development projects, the communication element can make or break a partnership. SupremeTech works with many companies from all over the world. Our expertise is mainly in the Japanese market. There were some initial challenges in getting used to communicating with a Singaporean partner, but our team overcame these challenges and worked smoothly and successfully with all members of the project. We used Today.ly to organize calls and meetings with our foreign partners because we felt that the product would help create cross-border collaboration. Developing Something More than A Video Call Tool The business idea was born during the pandemic, as were many online learning and work tools. However, we did not build Today.ly with a focus on online calls. We developed Today.ly to mimic more of the spontaneous happenings of the office. It was designed to function like an online office while allowing employees to enjoy the convenience and comfort of their home. We wanted to provide a virtual office that could strengthen the bonds of employees. This is not a video calling service; this is a virtual office that increases collaboration and teamwork amongst team members, even when they are physically separated.  But that was actually one of the main challenges of this project: how can we build something that takes advantage of the benefits of office work, but isn't redundant or completely useless in the market? The answer was to create an online space for communication, not just a communication tool. Nearly all companies use meetings to interact and discuss ongoing projects. For remote meetings, this means using a video call to communicate. There's nothing wrong with a regular video call; in fact, in some cases, it's probably more useful than any other method. Even if you think an email or message would suffice, meetings are inevitable.  Virtual Offices Doing More for Your Business! Sometimes a video call or DM just isn't enough; there's a technological barrier between us and the other participants. Today.ly simulates a meeting room in a way that feels more personal than talking heads in a square. It emulates the physical space. There's crystal clear audio, multi-screen sharing, and even a meeting table and chairs. Nothing can replace face-to-face communication, but Today.ly allows companies to mimic certain aspects while users are sitting in their own living rooms. It will always be a challenge to replicate the old-fashioned face-to-face dialogue, but Today.ly users have found greater motivation and connection within their teams.  Today.ly was initially for companies and industries that support working from home. The features were designed to make working online an interactive experience. While many companies have already returned to traditional office life, Today.ly is still a valuable tool for hybrid work environments and provides all businesses with an exciting alternative to traditional working environments.

How Agile Development Influences Developer And QA Tool Choices

On the surface, it might seem like the Agile methodology is simply about reimagining waterfall development by keeping an open mind. However, this approach has far-reaching implications for people, tools and processes. That said, let’s dissect the major Agile development characteristics that affect developer and quality assurance (QA) tool choices and talk about some great examples of Agile development tools: Increased Collaboration Agile development pushes for greater synergy amongst teams. It's hard to release higher-quality products faster if many of the people involved aren't openly communicating with each other about challenges. For example, a developer working alone can easily store, manage and reuse code using one machine. However, things get trickier once a project needs more hands and numerous software units are being created. You'll need a space where everyone's work can be converged, with changes indicated coherently. Photo by Tim van der Kuip on Unsplash  This is where tools like GitHub come in. GitHub will enable developers to combine their code into modules and easily perform version control. More importantly, developers can do all this remotely since it's cloud-based. It’s also worth noting that GitHub isn’t the only code hosting/management solution out there. You can always try others like TaraVault, AWS CodeCommit, Bitbucket, SourceForge, and many more. By the way, collaboration doesn’t begin only when the team has been formed. It’s an ethos that can be applied even when building the team and responding to talent departure or unavailability. With tools like Crowdsource.io, you can set up a project folder, post your needs and respond to interested developers. This social approach simplifies recruitment, especially during emergencies. Continuous Testing In continuous testing, teams don’t have to wait for all units to be ready before they start. Instead, they endeavor to test whatever small piece is ready as others are prepared. By doing so, they are less likely to be blindsided by complex problems in the software that delay a release as the team tries to fix them. This approach often means the testing workload will fluctuate as the project progresses, so quality assurance teams will have to be swifter at scaling testing capacity accordingly. One of the best ways to achieve this is by using test automation tools. Photo by freestocks on Unsplash More specifically, you'll need user-friendly test automation tools if teams are to quickly add new automations in response to changes in the testing workload. They should also facilitate reusability and easily plug into your CI/CD pipelines, which is what tools like Leapwork are good at. Additionally, an Agile testing team needs robust tracking and reporting capabilities to excel at continuous testing. This is where tools like JIRA and nTask Issue Tracker shine. They’ll offer features tailored to defect tracking while also helping you analyze QA team performance in real time so you can know how to increase efficiency and remain on schedule. Value-Driven Development You can only offer so much value if you aren't listening and responding to users. So to get better at value-driven development, you must create a smoother path for user feedback to be absorbed into the development lifecycle promptly. Photo by krakenimages on Unsplash One critical piece in this area is the usability testing tools you rely on. They should have functionality that speaks to agility, such as; Recruiting participants remotelyA/B testingIntegration with various tools like prototyping solutions, design tools, productivity tools and more. These are some of the crucial functions needed because: You want to be able to start user feedback collection from anywhere as soon as you get the green light. In that sense, participant recruitment should involve as little bureaucracy as possible and be easier to manage as you conduct more tests down the road. Testers should be able to compare feature variations side-by-side instead of testing one, then trying another later. So through A/B testing, you shorten the time it takes to discover whether a slight tweak in a feature caused a significant improvement in usability. Once you have user opinions and usability metrics, there shouldn't be that many error-prone processes to link the data to the concerned parties and the different tools they use to respond to the feedback. Whoever is going to modify a product should be able to quickly see how their previous contribution fared. The other leaders who have to sign off on additional changes should also be able to view this information simultaneously, so there isn't much sitting and waiting. Tools like UserZoom, Loop11, UsabilityHub, Userlytics and Maze will go a long way in helping you increase the customer value realized with each iteration. The glue that holds everything together While we’ve talked about the Agile QA process and Agile development software, another key aspect is more about the administrative side of an Agile project. When it comes to this area, you'll hear a lot of buzzwords and office terminology thrown around, like modularity, effective communication and visibility. But to be clearer about the tenets of organizational agility, here’s what Agile teams should emphasize during the development life cycle: Teams should be able to zoom in on the smallest of processes as this is how they'll know what's essential and what isn't and also what could be improved. Organizations should give more autonomy to the lower ranks so they can do some things at their discretion. If every small move has to first be run up a long chain of command, all in the name of maintaining control and minimizing risk, you can forget about faster releases. Whatever you practice should be incremental. For example, when figuring out how to communicate better, you don't just set benchmarks and lean back. Instead, you should revisit them to see if they are working and decide whether to maintain, increase, decrease or move sideways. So how exactly do these principles shape tool choices? Well, you’ll need Agile project management tools that offer features like automated notifications, workflow customization, analytics and recommendations. There are plenty of options to try; Agilean, ProofHub, ActiveCollab, MeisterTask, Axosoft, JIRA and DailyScrum. Wrapping Up Ultimately, tools that work for some may not work for you, so it starts with understanding your existing organizational culture and how much you're willing to alter it in pursuit of agility. That’s when you’ll know where tools are applicable and which functionality they must have.

Mastering AWS Lambda: An Introduction to Serverless Computing

Imagine this: you have a system that sends emails to users to notify them about certain events at specific times of the day or week. During peak hours, the system demands a lot of resources, but it barely uses any for the rest of the time. If you were to dedicate a server just for this task, managing resources efficiently and maintaining the system would be incredibly complex. This is where AWS Lambda comes in as a solution to these challenges. Its ability to automatically scale, eliminate server management, and, most importantly, charge you only for the resources you use simplifies everything. Hello everyone! I’m Đang Đo Quang Bao, a Software Engineer at SupremeTech. Today, I’m excited to introduce the series' first episode, “Mastering AWS Lambda: An Introduction to Serverless Computing.” In this episode, we’ll explore: The definition of AWS Lambda and how it works.The benefits of serverless computing.Real-world use cases. Let’s dive in! What is AWS Lambda? AWS Lambda is a serverless computing service that Amazon Web Services (AWS) provides. It executes your code in response to specific triggers and scales automatically, charging you only for the compute time you use. How Does AWS Lambda Work? AWS Lambda operates on an event-driven model, reacting to specific actions or events. In simple terms, it executes code in response to particular triggers. Let’s explore this model further to gain a more comprehensive understanding. The above is a simplified workflow for sending emails to many users simultaneously, designed to give you a general understanding of how AWS Lambda works. The workflow includes: Amazon EventBridge:Role: EventBridge acts as the starting point of the workflow. It triggers the first AWS Lambda function at a specific time each day based on a cron schedule.How It Works:Configured to run automatically at 00:00 UTC or any desired time.Ensures the workflow begins consistently without manual intervention.Amazon DynamoDB:Role: DynamoDB is the primary database for user information. It holds the email addresses and other relevant metadata for all registered users.How It Works:The first Lambda function queries DynamoDB to fetch the list of users who need to receive emails.AWS Lambda (1st Function):Role: This Lambda function prepares the user data for email sending by fetching it from DynamoDB, batching it, and sending it to Amazon SQS.How It Works:Triggered by EventBridge at the scheduled time.Retrieves user data from DynamoDB in a single query or multiple paginated queries.Split the data into smaller batches (e.g., 100 users per batch) for efficient processing.Pushes each batch as a separate message into Amazon SQS.Amazon SQS (Simple Queue Service).Role: SQS serves as a message queue, temporarily storing user batches and decoupling the data preparation process from email-sending.How It Works:Each message in SQS represents one batch of users (e.g., 100 users).Messages are stored reliably and are processed independently by the second Lambda function.AWS Lambda (2nd Function):Role: This Lambda function processes each user batch from SQS and sends emails to the users in that batch.How It Works:Triggered by SQS for every new message in the queue.Reads the batch data (e.g., 100 users) from the message.Sends individual emails to each user in the batch using Amazon SES.Amazon SES (Simple Email Service).Role: SES handles the actual email delivery, reliably ensuring messages reach users’ inboxes.How It Works:Receives the email content (recipient address, subject, body) from the second Lambda function.Delivers emails to the specified users.Provides feedback on delivery status, including successful deliveries, bounces, and complaints. As you can see, AWS Lambda is triggered by external events or actions (AWS EventBridge schedule) and only "lives" for the duration of its execution. >>> Maybe you are interested: The Rise of Serverless CMS Solutions Benefits of AWS Lambda No Server Management:Eliminate the need to provision, configure, and maintain servers. AWS handles the underlying infrastructure, allowing developers to focus on writing code.Cost Efficiency:Pay only for the compute time used (measured in milliseconds). There are no charges when the function isn’t running.Scalability:AWS Lambda automatically scales horizontally to handle thousands of requests per second.Integration with AWS Services:Lambda integrates seamlessly with services like S3, DynamoDB, and SQS, enabling event-driven workflows.Improved Time-to-Market:Developers can deploy and iterate applications quickly without worrying about managing infrastructure. Real-World Use Cases for AWS Lambda AWS Lambda is versatile and can be applied in various scenarios. Here are some of the most common and impactful use cases: Real-Time File ProcessingExample: Automatically resizing images uploaded to an Amazon S3 bucket.How It Works:An upload to S3 triggered a Lambda function.The function processes the file (e.g., resizing or compressing an image).The processed file is stored back in S3 or another storage system.Why It’s Useful:Eliminates the need for a dedicated server to process files.Automatically scales based on the number of uploads.Building RESTful APIsExample: Creating a scalable backend for a web or mobile application.How It Works:Amazon API Gateway triggers AWS Lambda in response to HTTP requests.Lambda handles the request, performs necessary logic (e.g., CRUD operations), and returns a response.Why It’s Useful:Enables fully serverless APIs.Simplifies backend management and scaling.IoT ApplicationsExample: Processing data from IoT devices.How It Works:IoT devices publish data to AWS IoT Core, which triggers Lambda.Lambda processes the data (e.g., analyzing sensor readings) and stores results in DynamoDB or ElasticSearch.Why It’s Useful:Handles bursts of incoming data without requiring a dedicated server.Integrates seamlessly with other AWS IoT services.Real-Time Streaming and AnalyticsExample: Analyzing streaming data for fraud detection or stock market trends.How It Works:Events from Amazon Kinesis or Kafka trigger AWS Lambda.Lambda processes each data stream in real time and outputs results to an analytics service like ElasticSearch.Why It’s Useful:Allows real-time data insights without managing complex infrastructure.Scheduled TasksExample: Running daily tasks/reports or cleaning up expired data.How It Works:Amazon EventBridge triggers Lambda at scheduled intervals (e.g., midnight daily).Lambda performs tasks like querying a database, generating reports, or deleting old records.Why It’s Useful:Replaces traditional cron jobs with a scalable, serverless solution. Conclusion AWS Lambda is a powerful service that enables developers to build highly scalable, event-driven applications without managing infrastructure. Lambda simplifies workflows and accelerates time-to-market by automating tasks and seamlessly integrating with other AWS services like EventBridge, DynamoDB, SQS, and SEStime to market. We’ve explored the fundamentals of AWS Lambda, including its definition, how it works, its benefits, and its application in real-world use cases. It offers an optimized and cost-effective solution for many scenarios, making it a vital tool in modern development. At SupremeTech, we’re committed to harnessing innovative technologies to deliver impactful solutions. This is just the beginning of our journey with AWS Lambda.
