Organizations in numerous industries are increasingly interested in and are attempting to build, real-time systems that far exceed the limited capabilities of the software systems of the recent past. The issues that these systems need to address impact internal operations and customer experiences, and also extend beyond the walls of the individual organization to change the expected capabilities of the industry, and even the health of the planet.
The next generation of real-time systems come into play in extremely diverse uses:
- Safety and security: Delivering new levels of health and public safety in smart buildings that automatically detect and stop the spread of disease,
- Retail: Enabling new personalized proximity marketing experiences in physical retail environments,
- Emergencies: Detecting floods and other emergency situations and then automatically triggering evacuation protocols
In all these scenarios – there can be no compromise in terms of responsiveness, reliability, and scalability. This demands that those in charge of development embrace a more modern way of thinking about the way these high-performance real-time systems should be architected.
When the Database First Way of Creating Real-Time Systems Fails — How Many Elevators Can You Actually Monitor — Before It Breaks?
A modern super-city might have buildings with hundreds of thousands of elevators – all of which require constant monitoring to detect situations of interest such as security and safety concerns. The best way to address this kind of ‘smart building’ challenge is through real-time stream processing that can handle data analytics at scale and deliver consistent and timely situational awareness.
Development would likely start with information from a single elevator with analysis done in a simple time-series database and small batch queries. But it would be incorrect to assume that what works for one should work for hundreds and then thousands.
The flaw in this assumption is that the database queries will be able to handle the explosion of data without massive loss in performance speed. This approach works as expected with a small number of elevators, but the whole system fails when the amount of data (elevators) grows beyond the capabilities of the database
Regardless of placing other real-time capabilities around the periphery of the traditional database in this system, the use of a database itself is what inherently breaks the system at scale.
The solution to creating a robust scalable system is to perform the analytics of anomaly detection in memory, and then move information to the database for historical purposes. The database is the last step, not the first, in a modern real-time system.
The Three Kinds of Real-Time Systems
While there is growing interest in real-time systems, there is accompanying noise, confusion, and misinformation about the different kinds and capabilities of real-time systems, as well as the relevance (or not) of databases to their ability to scale and perform as required. There are three types of real-time systems, each of which is relevant for solving a different class of problems.
- ‘Hard’ Real-Time Systems – hardware-based,
- Micro-Batch Real-Time Systems – ‘soft’ real-time systems that use more traditional data processes and queries,
- Event-Driven Real-Time Systems – ‘soft’ real-time systems that use stream or event processing.
1. “Hard’ Real-Time Systems
These types of systems are needed to solve problems that cannot tolerate any missing ‘deadlines,’ with performance speed measured in a few milliseconds. No database could ever deliver on this kind of performance, and in addition, all hardware equipment and computing need to be done on-premise. High precision automated robotic assembly lines require the rigor of this type of real-time system.
2. Micro-Batch Real-Time Systems
This approach to real-time systems is most appropriate for problems that only require some real-time processing with latencies in the hundreds of milliseconds (or even seconds,) and that require little scaling. eCommerce ordering systems can be a good match for this.
Traditional approaches to data processing are performed against small amounts of data (micro-batches) at a fast ‘duty cycle.’ Ground zero for creating fatal problems is found in attempts to scale the system and diminish the latency between batches to make these systems function, similar to event-driven real-time systems.
As the number of batches increases linearly, the compute overhead and cost to continually run the queries in the growing volume of micro-batches increases exponentially (up to the square of the database size.) At some point, the law of physics kicks in, and it becomes impossible to make the data analysis layer of the system perform in the defined ‘real-time’ at high volume. Ultimately, a database will never be as fast as event processing.
3. Event-Driven Real-Time Systems
This is the ‘goldilocks’ solution for applications that require action within a very short time period in the 1-10 millisecond range. A recommendation system is an appropriate use of this kind of real-time system – such as in eCommerce or in industrial automation.
In-memory processing, not a database, is the driving force in this system. Information (from IoT sensors, embedded AI, event brokers, etc.) is processed in flight using stream analytics, and it can then be sent to a database for historical purposes.
As the amount of data increases — the compute work scales linearly — not exponentially – as in the case of the micro-batch approach.
Finding and Avoiding the Performance and Scale Choke Points in Real-Time Systems
The analysis of the three types of real-time systems shows us that systems that use a traditional database storage model can never be scalable in real-time, even if the ingestion was real-time.
It takes time to perform queries, and query performance degrades as a database grows – which is exactly what happens when you try to scale a system. In our earlier elevator example, ingestion was real-time, but accessing and performing queries on the information stored in the database was NOT real-time.
The performance of that system was ultimately gated by the worst performing part of the entire system – the database.
In designing the next generation of real-time systems, it is essential to consider the time frame in which different information must be accessed and understood and the scale to which you ultimately want to grow your system.
It’s Not an Either-Or Decision — Next-Generation Real-Time Systems Will Need to Be Hybrid
There is not a one-size-fits-all approach to real-time systems. But it’s always important to start with understanding which information needs to be stored over longer periods of time in a database for historical reporting, deeper analytics, and pattern recognition.
Next, as opposed to the information that requires immediate action (on the order of milliseconds) for real-time event processing. The best systems will be those that combine the different models of data processing to take advantage of the benefits each offer.

Things to Keep in Mind Before Launching an Online Course
Within the last few years, the paradigm of traditional education has shifted radically. Being physically present in a classroom is no longer the only way to learn.
Now with the advent of the internet and new technology, you can get an excellent education wherever and anywhere you choose — as long as you have access to the internet.
In education, we are in the midst of a new era: the internet revolution
So if one wants to build a successful online course, one should keep certain things in mind.
First, you need to be educated in the field you want to teach. Get validated in that field. What have you determined to teach and where is your stronghold? For that, you have to make a note of certain things that would form the foundation in designing your course, such as :
- Find your area of interest. Your course should be dedicated to something you love. Your content will be less engaging if you fail to connect with it. And due to a lack of interest, your way of content delivery might be too dull for your students. So, find the area in which you are keen to work.
- List your skills. Make a list of the skills you possess. This gives you a clear idea of your area of expertise.
- Experience and achievements. One’s experience and achievements reflect how well they have practiced the skills and how good they are in applying them.
Now you can filter out the courses you can provide and then find the audience for it. The next step is talking about the audience. But before moving on to your course, keep in mind that the audience might not want the things you like or the area in which you are good.
Identify your target audience and their needs
No one will purchase a course just because you have an interest in making it. One would only buy it if and only if it could add value to their life. So, find who is the target audience for your content and is. Is there enough market demand for it? You must study who would want your course because finding a way to make your course profitable to you matters and will motivate you to do better and provide finer materials for your students.
Now, in order to find if there is market demand for your product, you can make use of your computer and Google research and use the Google analytical tools. These include:
- Google keyword planner.
- Google Trends
Also, you can use sites like Reddit and Quora for the same type of research. Using these two sites gives you a detailed view of how many searches are made for your topics. From this research, you can estimate your current market demand and the level of competition in the market.
Before designing your product, it is crucial to conduct a competitor analysis. Checking out your competitors will help you to identify the ins and outs of your competition. And never underestimate where you can find some additional ideas to add to your own course. Competition provides that little extra info.
You can research the competition by going through the marketplace and identifying what your competitors offer, and trying some of their products. Put yourself in the shoes of customers and find out what are the strengths as well as the flaws of their product. Also, capture the reviews of their customers. By checking out the reviews, you can design your product in such a way that it eliminates the gap between your competition.
Design your course
Now that you have done a complete evaluation of your competition and the product offered by them, it is time to design your product. Keep in mind that your course should create differentiation, and it should have a unique value proposition. Looking for the things that the audience is unable to find in your competitor’s course will help you cover those areas in your course.
Create your course and make it compelling and engaging for your audience. Although your course might be full of information, if your audience gets bored, they might shift to other courses. Contextualize your course and weave cohesiveness with your audience.
Your audience should find your course practical and applicable in their life. Observe your course through how your audience will perceive it. Some tips to make your content engaging are:
- Make your lessons more pictorial
- Add storytelling methods to deliver content
- Create learning groups
- Conduct live Q/A sessions
- Add more practical examples and applications to your course.
- Add a reward-based learning system, i.e., award rewards for students who complete certain tasks in the course
Before you launch your course, go for product testing within a small group and collect their reviews. Then evaluate the areas and make improvements. This decreases the chances of product failure.
Launching your course
You should launch your course as soon as possible — others might be thinking of doing the same thing you are. Strategize a pricing model for your online course. Your course should not be seen as a cheap product as that will create a bad perception.
Make your course accessible to a wide range of audiences by making it available on relevant platforms. Create a launch trigger so as to create a buzz among your target that something interesting is coming. Amplify your audience enrollment by offering various redeemable vouchers and coupons.
Many creators think that once their content is launched, it will sell on its own. But the best product in the world does not launch itself. If your product does not reach your customer and they don’t get aware of it — you will not have a course to sell.
Generate the leads for your course through:
- Backlinks in blogs
- Early bird discount promotion.
Your course has been launched — but it is not over yet. Do not resist changes in your course module — just do what has to be done to make your course a success. Gather feedback from your audience regularly and work on making your course what your customers/students will like.
Revise your course within a certain time interval. It is important to make these valuable changes in order to retain your existing audience and stay ahead of your competition.
Online education is typically less expensive than in-person education. Online, there is frequent access to a wide range of material such as videos, photos, eBooks, and tutors. These platforms can also incorporate other formats, such as forums or discussions, to improve lessons.
You can study or teach from anywhere in the world with online education. This means that there is no need to commute or adhere to a strict schedule. And current online enrollment in professional courses is around 1.38 Billion, and the number is increasing in rapidly.
Muvi Live is an end-to-end streaming platform that provides on-demand and live-streaming solutions for the educational sector, including institutions, universities, and ed-tech companies.
Equipped with a range of services in a virtual classroom, you can create, upload, and monetize online course content with ease. You will want to be mobile optimized and have a chat feature and collaboration features.
You will also want to smoothly integrate with LMS (learning management system) through API and SDKs for real-time assignments, tools, PowerPoint, etc., and provides an intuitive learning experience in one place.
Use analytics within your course so that you can evaluate the performance of students as they move through your course materials.

7 Questions You Must Ask Before Hiring a DDoS Mitigation Provider
There is nothing worse for your business continuity than a sophisticated dedicated denial of service attack. Cybercriminals can send a barrage of malicious traffic to overwhelm your servers and make them incapable of responding to legitimate requests. This can make your website inaccessible and bring your entire network down to its knees.
Even though the duration of DDoS attacks might not be as long as before, they are growing both in numbers and intensity. If you don’t have the right protection in place, your website could go down for days or even weeks. To prevent that, businesses tend to hire DDoS mitigation service providers.
These DDoS mitigation service providers have the resources, skills, and experience to identify and block these attacks. Sadly, not all of them are equally good, which is why you need to do your research before hiring the best DDoS mitigation service provider. In this article, you will learn about seven questions you need to ask before hiring a DDoS mitigation provider.
7 Questions You Should Ask Before Hiring DDoS Mitigation Service
1. What is Your Deployment Model?
Every DDoS mitigation service provider follows a unique model. Make sure that their deployment model aligns with yours — otherwise, the mismatch could lead to even more issues down the line. The most common deployment model DDoS mitigation service providers use:
- On cloud
In an on-premise deployment model, a device is installed which analyzes traffic before reaching your network. This can be a great option if you want to safeguard against low and slow attacks. On the flipside — cloud-based deployment models use scrubbing centers, which monitor the traffic before it reaches your network.
The benefit of the cloud-based deployment model is that you don’t have to install any wearable device. Lastly, the hybrid deployment model gives you the best of both worlds by blending both approaches together. The deployment model you choose should depend on your risk profile, type of attacks, and on-premise installation.
2. What type of Cybersecurity Attacks Can You Protect Against?
There are many different types of DDoS attacks. Each of them targets a different layer of your technology stack. Each type has its own carrier and mitigation techniques. This is where your prospective DDoS mitigation service provider can come into play.
Most DDoS protection providers can prevent DDoS attacks by blocking attackers from flooding your network with illegitimate traffic. What really differentiates great DDoS mitigation service providers from the rest is their ability to efficiently handle attacks at other layers of the technology stack as well.
Hire a DDoS mitigation service provider that can prevent attacks at higher layers that utilize more protocols such as UDP, TCP, tunnel HTTPS, and SSL. Some DDoS attacks also leverage compression and encryption protocols, while other attacks target the application layer with HTTP GET and POST commands to create congestion in your network.
3. How Much Control and Visibility Do You Have Over the Network?
Hire a DDoS mitigation service provider which owns the core of its network with multiple points for analysis. The prospective DDoS protection service you are planning to hire should have a vast network of scrubbing centers. This gives them the capability to find and neutralize the harmful effects of DDoS attacks. Even if the malicious traffic originates from multiple sources simultaneously, it can block all the malicious traffic.
4. What is Your Total Network Capacity?
As I mentioned before, DDoS attacks are growing in frequency and becoming more sophisticated, but they are also becoming larger in nature. You don’t want to hire a DDoS protection service that is not capable of handling a large-scale DDoS attack.
Ask the service provider how much network capacity they have and the maximum size of DDoS attacks they will be able to block. The higher the network throughput, the more capable the DDoS mitigation service is. Another question you need to ask is how rapidly the scrubbing centers can analyze and forward the packets. The faster the speed, the more efficient the DDoS protection.
5. How Quickly Do You Respond?
A dedicated denial-of-service attack not only makes your website inaccessible but can also disrupt your business continuity. The longer a DDoS attack lasts and keeps your website offline, the more money you will lose in terms of sales and revenue.
This is why it is important for businesses to work with service providers who can respond to DDoS attacks quickly and restore business operations as soon as possible. The faster they can detect DDoS attacks, the higher chances they have of minimizing the damage. Ask the service provider how fast they can detect attacks and divert incoming malicious traffic.
6. What is Your Pricing Structure?
The cost of DDoS mitigation depends on a variety of factors. Two of the key factors include the time and bandwidth required to repel DDoS attacks. Every DDoS protection service provider follows a different pricing model and charges different rates.
Some might charge you a fixed fee for their DDoS-protected dedicated servers, while others have variable costs attached to them. Assess your needs and risk profile before choosing a service provider that offers a pricing structure that meets your needs perfectly.
7. What Will You Need From Us?
You also need to know what the service provider needs from you. Is their solution easy to set up and use, or does it have a steep learning curve? Ask whether you need to switch to a new internet service provider or make changes to configurations.
Is installing hardware on-premises mandatory? If yes, then how difficult is the setup and installation process, and how much time will it take to get operational? Once you get answers to all these questions, it will be easier for you to choose the best DDoS mitigation service.
Which questions do you ask when opting for DDoS protection? Feel free to share it with us in the comments section below.
