Serverless computing: everything you need to know



There is a technology that is present in the execution of almost all the activities we carry out on the Internet: cloud computing. Cloud storage consists of storing information managed by an organization or company on servers external to it and to which the company itself can access at any time and remotely. For example, when you access your banking information you are using cloud computing without realizing it.

Cloud computing has given companies greater storage capacity and computing power. Only in Spain, in the first quarter of 2021, 32.4% of organizations with 10 or more employees purchased cloud services, according to the Survey on the use of ICT and electronic commerce in companies. These data show that today’s companies are always looking for new ways to improve their processes improve their productivity and reduce the costs of deploying and managing their applications and/or services. As is the case, the use of the cloud, since it offers greater security for your dataas well as greater performance .

In this scenario, in recent years there has also begun to talk about a new computing paradigm: serverless computing or computing without a server. Contrary to what it means, it is not a serverless architecture, but software developers -those responsible for deploying applications in the cloud, which could be considered customers of the cloud provider (Amazon, Google, Salesforce, etc.-, they don’t have to worry about configuring or managing the servers because those tasks are taken care of by the cloud provider.

Even though this serverless computing has been on the market for years, it has not been until now that it has reached its peak. From Telefónica’s Research area, Eduard Marin, together with other people, investigates the benefits and disadvantages that this type of technology can bring to companies. “ Our goal is to significantly advance the state of the art to make serverless computing much more secure than it is now,” says Eduard.

What is serverless computing?

When we mention serverless computing, we are referring to a new paradigm that in the future is likely to become the dominant way to deploy applications in the cloud. Applying edge computing, that is, when we bring the processing as close as possible to where the data is being generated.

In serverless computing, application logic is broken down into a set of small, ephemeral, stateless functions that communicate with each other and with various cloud services (for example, storage services) to accomplish their tasks. Today’s serverless architectures are often event-driven. In this way, functions can be executed on receipt of a wide range of events. As happens when new data is added to a database, when receiving an email, or when obtaining a new measurement from a sensor, among others.

The serverless computing model separates itself from monolithic systems and microservices, offering a form of payment for the resources that each application consumes. This is a noticeable difference from previous cloud models, where users pay a fixed amount for the resources allocated (regardless of the resources the application consumes). In addition, this ecosystem is developed according to the needs of the organization, so it is not necessary to make a large outlay of capital. Currently, there is a lot of research that is focused on analyzing the properties that serverless offers and improving it further to be able to support a greater number of applications. Our work focuses on investigating the security offered by this serverless model.

2 models of serverless computing

Along these lines, thanks to the effectiveness of the serverless method, today we can distinguish between two types of architectures: Function as a Service (FaaS) and Backend as a Service (BaaS).

  • BaaS is a service that automates back-end development, through third-party services and applications. The central idea behind BaaS is to offer software developers a set of services and tools (databases, APIs, file storage, etc.) to facilitate and speed up the development of mobile and web applications.
  • FaaS is a model that focuses on allowing software developers to deploy and run their functions in the cloud. Here, the functions can also use additional services, such as those offered in BaaS. At the moment, FaaS is considered the most dominant serverless model.

Advantages of implementing a serverless computing model

The implementation of serverless computing offers numerous advantages to the user. Some of them we have already mentioned throughout the article, others are the following:

  • The serverless model allows software developers to outsource all infrastructure management as well as operational tasks to cloud providers, allowing them to focus on writing the code for their applications.
  • It follows a pay – as-you-go model, that is, it is only charged based on the resources consumed.
  • It offers fast, unlimited automatic scaling of resources up and down to match demand, from zero to virtual infinity.

    Green computing or green computing

    Green computing stands out among the benefits of integrating this type of architecture. A new paradigm arises to execute a greater optimization of computing resources in companies but with the least possible impact on the environment.

    Coping with climate change by reducing energy consumption, the carbon footprint, etc., has become one of the main concerns of society. Microsoft, for example, has taken action on the matter with the launch of a data center, where most of the energy comes from renewable sources.

    Security in the serverless model

    Under this sustainable aspect offered by the serverless model, we must delve into one of the questions developed around this technology: is serverless computing secure? Well, the first thing to be clear about is the ecosystems around which this architecture is developed are complex, dynamic, and made up of many different components. For an ecosystem of this type to be secure, it is necessary to make sure that the components and the interaction between them are secure.

    This area of ​​security has been investigated by the Telefónica Research team. The article Serverless Computing: a security perspective, developed by Eduard Marin, Diego Perino, and Roberto Di Pietro, addresses the current situation of serverless computing in terms of security. Demonstrating throughout the text the type of current threats to which this type of architecture is exposed, as well as those additional security features offered by the serverless model.

    The first distinction to be made is the differentiation between external and internal adversaries. The external ones, as the word says, carry out attacks from outside the cloud. These can allow opponents to execute arbitrary commands to obtain sensitive data or manipulate the execution of any function. Whereas, internal adversaries are those that run from within the cloud. For example, in the case of a public cloud, it is significantly easier to execute malicious functions.

    Characteristics of serverless computing

    One of the handicaps of the serverless model is that its functions can be activated from various sources, expanding the attack surface. Each of the functions that run within this architecture performs a single task and is therefore forced to interact with other shared cloud services, even though there are security policies that specify which functions and services in the cloud you can access each function, being such a complex environment, security policies are prone to configuration errors that open the door to security attacks.

    Most of the security responsibilities for serverless computing fall on cloud providers. Whereas, software developers are responsible for maintaining security at the application level. Therefore, for them, it is vitally important to follow the best security practices when writing serverless functions to reduce the chances of bugs -software defects- in these, which may lead adversaries to launch attacks.

    However, this architecture offers greater resistance against various types of Denial of Service (DoS) attacks that aim to saturate network bandwidth, trigger many heavy computing actions in parallel, or exploit application flaws. , for example, to cause infinite loops. That is a failure that consists of carrying out a cycle that is repeated infinitely because its condition to end is never met.

    Even though this technology saw the light of day at the Amazon Web Services event in 2014 and various cloud providers have entered the world of serverless platforms, there is still a lot of work ahead. One of the main challenges is the security of this model. “ With the increasing volume and diversity of attacks against the cloud, we believe that security and privacy will be a key factor that, if not addressed, could hinder the widespread adoption of serverless computing,” the team explains. fromResearch.

    Toward a serverless cloud

    For the moment, we can say that we are facing an evolution in the development of applications in the cloud without a server. Where there is still much to investigate, learn and apply. Serverless computing is a challenge in itself that requires design decisions related to service monitoring (QoS), scaling, and fault tolerance ownership to be handed over to the cloud provider .

    Serverless computing has been created, above all, for the rapid exchange of data from web applications and businesses in the cloud. Therefore, initially, it does not consist of processing entire applications, but rather separate functions. Some of the scenarios where it could be introduced due to its characteristics are:

    • Backend as a Service (BaaS) to build and support the back-end of a cloud function.
    • Performing tasks after the detection of an event, such as creating backup copies or reorganizing databases.
    • Integration of chatbots and conversation assistants.
    • In the field of big data, where the serverless model is positioned as an ally to combine, move, manipulate, etc., unstructured data (audio, images, etc.) and structured data (XML, JSON, etc.).

Equipment Repair Services: DIY vs. Professional Assistance



Equipment Repair Services

While DIY repairs and maintenance can be rewarding, it’s essential to assess your skills and the complexity of the task. For complex repairs, hiring professionals can save you time and money. Consider a preventative maintenance plan instead of a reactive maintenance strategy, which relies on equipment to break down before it’s repaired. It will keep minor issues from escalating and costing you more.


Hiring professionals may be the best option for equipment repair services in Lafayette AL, especially if the task is complicated. Their specialized knowledge, access to technological tools, and compliance with regulations ensure that the work will be done safely and to a high standard.

A company’s production processes depend on equipment functioning correctly. When a machine fails, it slows the entire line or halts output entirely for days or weeks. Not only does this affect productivity, but it also creates unsanitary working conditions and increases operational costs. Lab equipment is vital to any scientific research or development. With proper maintenance, the performance of these tools can improve, resulting in accurate data and spent time. Equipment repair services can recalibrate and repair these instruments, ensuring they are always ready for use. They can also lengthen their lifespan. Regular maintenance helps protect a manufacturer’s warranty and reduce future repair costs. This type of maintenance is known as preventative maintenance.


Equipment repair is a critical part of maintaining a business. With it, they can retain products, money, reputation, and potential customers. However, equipment repair costs can vary depending on the type of machinery involved. For example, repairs to a heavy construction machine will differ from those performed on an automated food processing system. Ideally, your company should use a preventative maintenance strategy for its equipment. It ensures that minor issues are fixed before they become more significant problems, saving you money in the long run. However, many businesses still take a reactive approach to equipment maintenance. It can result in costly downtime, high repair costs, and a lower resale value. To minimize equipment downtime, invest in a preventive maintenance service plan. Some service plan follows OEM-recommended preventive maintenance guidance and helps extend the life of your equipment.


Professionals have the experience and expertise to complete the repair promptly. They also have access to specialized tools to help speed up the repair process. In addition, professionals are trained to follow safety protocols and can provide advice on the best way to maintain equipment. An up-to-date maintenance checklist can help reduce the time needed to repair or inspect. A checklist that includes standard operating procedures (SOPs) is essential so your team can easily refer to them when performing maintenance tasks.

Running equipment until it breaks down or run-to-failure maintenance can result in costly repairs and downtimes. It’s essential to use a preventative maintenance program to reduce these costs and keep critical equipment like defibrillators, power generators, pumps, and tools in good working order. If you choose to work independently, you’ll need to factor in the time it takes to move furniture and wall decor and clear a path for the technician.


It takes work to keep up with equipment maintenance schedules. It’s true when you have a fleet of cash automation, self-service, and other technology that includes multiple devices from different manufacturers. It requires a robust service technician footprint, planning, and logistics to ensure the correct parts are available when needed. Intermittent failure occurs due to normal equipment wear and tear, but it can be avoided with routine maintenance and preventative services. It includes lubrication, proper fastener tightening, and avoiding collisions or overexertion.

Running your facility with a local maintenance and repair provider can reduce costly, unscheduled downtime. That’s because technicians can catch issues that aren’t always obvious, like a small crack on the screen or an air filter that needs to be replaced. It can help save costs by reducing the required repairs and lowering equipment replacement expenses. It is also important because some equipment warranties require detailed service records.

How to Choose the Right CNC Parts for Your Project




Choosing the right CNC-machined parts for your project requires careful consideration of numerous factors. This process can be complex and intimidating, but a knowledgeable partner can help you navigate the process successfully.

The material of your CNC parts will depend on how they will be used. You are selecting a material that meets your design prerequisites, such as strength profile, operating temperature restrictions, and fitment requirements.


The material you choose for your CNC parts can impact its quality, durability, and cost. When selecting materials, it is important to consider the purpose of the part and its working environment. For example, a product used in a high-humidity climate may require corrosion-resistant metals. Other factors must be considered include the material’s tensile strength, hardness, and corrosion resistance. You should also consider whether the part requires fastening and, if so, what type is required. It is also essential to choose a material that can support the operating temperature range of your product. The machinability of the material should be considered as well. Certain metals are difficult to machine and can damage the tools. For this reason, you should choose a material compatible with the CNC machining process. The material must also have the ability to maintain tight tolerances. You can use plastics such as polyoxymethylene (POM), acetal, and nylon for this.


Defining tolerances is essential when designing a new product. A small mismeasurement can render a part functionally useless or incompatible with other factors. Fortunately, skilled contract manufacturers have the resources to estimate tolerances and ensure that your products are compatible accurately. The lower tolerance limit tells the manufacturer how much smaller a measurement can be from its nominal value, and the upper tolerance limit indicates how much larger a size can be. This is a standard way to specify tolerances for linear dimensions. A higher tolerance can increase the cost of production because it requires more time, skill, and expensive tools to create parts with a high degree of precision. However, a tight tolerance is necessary for some products, such as moving parts that fit snugly inside other components. Loose tolerances are not ideal for products requiring a close fit because they can cause leg friction. Moreover, they can also compromise the quality of the finished product.

Lead time

When looking for a CNC machine shop, it’s important to consider their lead time. This is how long it takes them to complete your project, from receiving 2D drawings with all details, tolerances and measurements to shipping your finished part(s). Many factors can affect lead times. For example, tight tolerances require additional machining operations and manual adjustments, which can increase costs and time. Another factor is the sequence of operations. To minimize lead times, it’s recommended that you design parts for efficient machining by grouping similar functions and avoiding features with difficult access. Finally, reducing lead times can be achieved by establishing service level agreements with key suppliers, sharing demand forecasts and setting realistic safety stock levels. Additionally, local sourcing lowers shipping costs and can improve the availability of components during disruptions. Finally, using just-in-time delivery methods allows for faster production by minimizing inventory holding time.
