Cloud computing is spreading around the world, as it is an increasingly popular technology. The reasons are simple: it allows greater productivity and security in all jobs. However, did you know that there are different types of cloud computing? In this article, we will tell you everything you need to know about it, including what each one is for.
Types of Cloud Computing you need to know about
First and foremost, it should be noted that there are 4 types of Cloud Computing. We could say that they are the following: public clouds, private clouds, hybrid clouds, and multi-clouds. Similarly, it is essential to point out that there are 3 types of Cloud Computing services: Infrastructure as a Service (IaaS), Software as a Service (SaaS), and Platform as a Service (PaaS).
But what are the similarities between each? They all extract, pool, and share computing resources on a network. All clouds enable cloud computing, which is a system that runs workloads. Therefore, they usually include an operating system, a management platform, virtualization, or automation, among other elements.
However, there are also several differences. Let us tell you about them:
According to TechTarget, public clouds are usually created from an IT infrastructure external to the end-user. For example, some well-known providers are Google Cloud, Amazon Web Services (AWS), and IBM Cloud. Until some time ago, public clouds were run off-site.
However, today’s public cloud providers started offering these services in their customers’ on-premise data centers. So when do clouds become “public”? When environments are partitioned and become distributed among multiple users.
As for private clouds, they consist of cloud systems that are specifically targeted toward an end-user but can also be a group of them. This means that many clouds can become private clouds in cases where the IT infrastructure is intended only for one customer, in isolation.
However, it should also be noted that companies are now designing private clouds in third-party, off-premise data centers. In other words, private clouds no longer need to come from an on-premise IT infrastructure. And did you know that there are two subtypes corresponding to these clouds? They are:
Exclusive clouds. It is a cloud within a cloud. You can have an exclusive cloud in a public cloud, but also a private cloud. This happens in large enterprises. For example, the accounting department can have a dedicated cloud within the corporate private cloud.
Managed private clouds. In this case, customers create and use a private cloud that is managed by an external provider. This type is perfect for those companies that do not have the resources or skills necessary for companies to self-manage, as they rely on a specialized company.
In this case, it is a mix of both of the above options. Google defines hybrid clouds as IT environments that are created in multiple environments and are connected via local area networks (LANs), wide area networks (WANs), APIs, or virtual private networks (VPNs).
And what are the characteristics of these clouds? Well, they are usually the most complex. A hybrid cloud, similarly to other hybrid models, is made up of a mix of elements. In this case, it usually has at least one private cloud and one public cloud. It is also possible to have two or more private clouds, two or more public clouds, and a virtual environment connected to a cloud, usually with an operating system.
This allows us to understand that IT systems are transformed into hybrid clouds when applications are moved to different environments. All these digital environments need to be managed as a single environment, through a platform that is integrated into the organization and management.
Finally, there are also multi-clouds. This is a specific type that consists of at least two cloud services. In this sense, at least two public or private cloud providers are provided. And it is important to clarify one thing: all hybrid clouds are multi-clouds, but not all multi-clouds are hybrid.
Only, they become hybrid when several clouds are connected through some integration. The digital multi-cloud environment can be created on purpose. One case occurs when sensitive data needs to be controlled. They can also be generated randomly, after using software not approved by the company.
So, you have seen that there are different cloud computing systems. No cloud is “better than another”, but it will always depend on what is needed in a company. In other words, all of them can be useful, depending on the different contexts. For this reason, it is key that you know what your intentions are when hiring this software. In short, we have analyzed the different types of cloud computing and what you need to take into consideration when opting for one of them. Keep this article handy for when you need to implement the cloud in your company!
Today, companies can draw on many valuable technology resources, such as a DevOps Toolset. However, perhaps the most obvious case is DevOps resources. This set of IT practices will allow you to work more efficiently. But which are the most successful tools? We will tell you in detail.
The best DevOps tools you need to know about
The first thing to point out is that this market is really interesting. According to a report by DZone, the DevOps market will generate about $6.6 billion by 2022. More and more organizations are implementing it at different scales, and you should be one of them.
In this sense, don’t you know what this concept means? Well, it encompasses all the practices, work philosophies, and tools that allow organizations to offer IT services in a more efficient way. By adopting this philosophy, customers can be served with quick corrections, gaining a competitive advantage in the market.
All this means that companies that incorporate this work culture, through different tools, are better able to meet their objectives. After all, they can optimize their products and services, with fast development processes. Do you want to know which are the best tools? Let’s develop your DevOps Toolset. We will tell you about them below.
Jenkins is an open-source automation server that you need to consider in your DevOps Toolset. But how does it help companies? Well, it’s easy: it serves to automate all software development processes. For this reason, this tool allows teams to monitor recurring tasks, integrate changes easily and identify problems quickly.
Jenkins allows you to use more than 100 plugins, which can be integrated with many current tools. This standalone program was written in Java and runs on Windows, Linux, or macOS. In addition, Jenkins can be configured via a simple web interface with integrated help.
Let’s continue with another resource that you can take advantage of. Docker is used by more than 11 million developers around the world. This tool allows you to build, package and deploy code simply and dynamically, to improve work productivity.
Docker eliminates all configuration activities, focusing on fostering team collaboration. In this sense, Docker allows developers to run in the development environment and operations teams to perform various tests and deployments.
It has several notable features in its favor. For example, Docker can use virtualization on the operating system to deliver containerized apps. In addition, it works with GCP and AWS, simplifying migration to the cloud. On the other hand, it also integrates seamlessly with other tools, such as GitHub or CircleCI.
Puppet is an open-source tool for improving software configuration management through automation. This tool works to manage the different stages of the software lifecycle. For example, provisioning the IT structure, applying patches, and configuring software components.
Among its main features, Puppet is developed in C++, Clojure, and Ruby. For this reason, it runs smoothly on Windows, Linux, and Unix. It also uses declarative language, which is used to define the system configuration. And, to top it off, it reduces manual errors, allowing your team to scale IT infrastructure.
Developed in Java, Apache Maven is used for projects that have also been created in Java. And what does it work for? Well, simple: it seeks to manage and understand projects. It helps in the construction, reporting, and documentation of the various projects.
Apache Maven has predefined targets for compiling and packaging code. You can also download Maven plugins and Java libraries so that the development process is as fast and efficient as possible. In addition, you have automatic updates and dependency closures.
Bamboo is also used to link builds, releases and automated testing. All in one workflow! Thanks to this tool, you can create multi-stage build plans.
You have two versions: an open source one and a paid one. If you develop an open-source project, there is no need to pay. On the other hand, for commercial organizations you’ll need to purchase subscriptions. Anyway, its intuitive user interface, auto-complete features and automation processes make it worth the investment.
Finally, you can also take advantage of Gradle. It allows you to speed up the productivity of all software developments. Gradle is built in Java, Kotlin, and Groovy, and is used to automate different aspects of projects. For example, software development, testing, and deployment.
Gradle has a very advanced ecosystem of integrations, in addition to different plugins that allow systematizing the software delivery throughout the entire life cycle. Gradle allows scaling the development through fast builds, and it is so versatile that it can be used by large companies and also by startups.
In short, you have seen that there are many DevOps tools that you can take advantage of for your business. As you have seen, they will help you to achieve better and better results, and we hope this article has been of great help to you!
Are you learning to program and need some help? Don’t worry: we’ve all been there. In this case, we will tell you which are the best ideas for coding in Python. We assure you that, after reading this article, you will have better references to make your work routine or learning more bearable.
Programming in Python: an excellent option.
First of all, something essential: Why should you choose Python over the other options? Let’s start by describing its virtues. According to Simplilearn, Python is one of the most popular programming languages of the moment. Although it was created in the 1980s, today it is extremely useful and versatile for different projects.
Now, why might it be a great option to learn it? According to TechVidvan, one of its main strengths is that it’s easy to read, learn and write. After all, those will be the procedures you will be doing both when learning and working. Therefore, if you have never had experience in programming languages, this may be your option.
There is also the job field to consider. Python is one of the most sought-after languages by employers. So, this means one thing: that, if you learn Python, you will be able to get a stable and quality job. But that’s not all! There is also an immense virtue, which is its flexibility.
As it is a general-purpose language, it can be used for different projects. It is not a specific language for web development, for example. In fact, with Python, you will be able to create all kinds of programs and tools. Moreover, Python is interoperable with other languages, such as Java, C, or R.
All of this means that Python can be a perfect solution for those who want to get started in programming. If you want to program, but don’t know specifically what to do, learning Python will give you a general overview of this. Also, once you know your tastes, you can specialize in a particular branch.
Essential tips for coding in Python.
That said, it is also likely that you want to know some secrets to learn how to program in this language. Here we will tell you the most important ones:
Write in code daily.
This is one of the perfect tips for those who are taking their first steps in Python. Perseverance is key to success in learning this language. You might start, but then you don’t have the motivation to continue. This is a mistake! To learn Python you need to write every day.
Memory is key to learning to program and you don’t need to take too much time either. For example, you could consider starting for 30 minutes every day. From a certain point on, you will feel looser and you will be able to perform more and more complex developments. You already know: consistency is very important.
Don’t forget to take notes.
Yes, we know that many doubts will arise while you are writing code. The truth is that you shouldn’t keep those questions in your head: write them down! When you write them down, you are reminding your brain that there are things you need to find out. Fortunately, the Internet can give you the answers.
Python is one of the programming languages with the best communities. Being open-source, you will also have many resources to take advantage of. In addition, it is important to keep in mind that doubt can help you improve your knowledge. Therefore, you should awaken your “curious” side.
Interact with databases.
This is a slightly more technical tip, but just as important. When you learn Python, you’re going to have to interact with basic data structures, such as dictionaries, strings, or lists. You might also be debugging an application. Consequently, the Python Interactive Shell is going to be your best friend.
Rest is also important.
Python is a truly engaging language. Since it has a low difficulty curve, you might be able to do a lot of things in a short time. That might make you want to learn more and more, but don’t forget to rest! A developer who is not very “lucid” may have a lower frustration tolerance and be less productive.
Don’t get frustrated by mistakes.
We know that making mistakes is a bad thing, but it’s also part of being human. And you have to accept the reality: you will make mistakes once, twice, a hundred times… You can have many years of experience and make basic mistakes. What’s important is to take notes to avoid repeating them in the future.
In short, you have seen that coding in Python can be a great opportunity for those interested in programming. If you follow these tips, your experience is likely to be very positive and you will be able to create great things. We hope this article has been helpful to you!
You may be interested in finding new and more efficient ways to develop software. Especially if you work in teams, which is one of the keys to achieving better quality developments in the shortest possible time. In this article, we will tell you what Scrum is and why it can be the methodology you need in your work routine.
What is Scrum and why is it a great methodology?
According to Business News Daily, it is a methodology that seeks to foster collaboration between development teams. The name of this kind of work process comes from rugby, where all the players must work together to obtain the team’s victory, and it is the same thing that happens in software development!
The idea of the Scrum methodology is to obtain the best possible result from a given project. But that is not it: it also appeals to efficiency and productivity. So, not only results are sought, but also the lowest possible cost and time on each of the jobs.
One of the keys to Scrum is partial deliveries. Some teams tend to base their developments on final deliveries to customers, but this is usually a mistake. Do you wonder why? Well, for several reasons. The main one is because there is no certainty about whether the development will be liked by the customer.
Therefore, you can spend hours working on one thing that you will later have to modify completely. On the other hand, with the Scrum methodology, you make partial and periodic deliveries. Consequently, the customer will be notified of all the progress and will be able to request revisions or modifications while you are working.
However, this is also very important to improve efficiency. As you make partial deliveries of the final work, you will always keep priorities in mind. Consequently, the workflow always focuses on the main thing first. Then, details are added on top, which is perfect for complex projects.

Benefits of developing software in Scrum.
According to Indeed, the Scrum methodology has many benefits for teams. Here are the most important ones:
Better sizing of projects.
In Scrum, iterations guide projects. Consequently, each project is divided into small blocks that are much more manageable. This situation is perfect for those complex developments, whose dimensions can be overwhelming for programmers. Here, on the other hand, every stage, every goal, and every possible difficulty that may appear along the way is known.
Improve delivery dates.
We know: that deadlines with the client can be a problem. Sometimes they are anticipated due to unreasonable development expectations and then have to be changed in the end. Well, nothing like that will happen here. Thanks to these project divisions, error margins are less frequent and this allows a more realistic development.
Do not forget one relevant thing: Scrum is a group methodology. Most iterations are usually resolved between 2 weeks and 1 month, although it will depend on each work team. Therefore, it focuses on each stage quickly and this means that developers will learn more things in less time.
The Scrum methodology also makes it much easier to receive feedback from the customer or the Team Leader himself. Since the work blocks are smaller, it is easier to acquire accurate feedback and propose quick solutions to possible setbacks. This prevents errors from being carried over to the final product.
Generation of an MVP.
Yes, you will also be able to generate an MVP (Minimum Viable Product) through this technology. After several iterations, you will have a functional product to deliver to the customer. As you will always seek to develop the essential aspects of the software, you will surely have that MVP much sooner than with another methodology.
Finally, you must consider that there will be certain orders and responsibilities that cannot be avoided. However, in general, segmenting the work with this agile methodology will mean an increase in freedom for the programmers. Consequently, they will be more comfortable solving each of the tasks.
ISA case: SCRUM in a real Huenei project.
To illustrate the importance of the Scrum methodology, we want to tell you about our experience working with one of our clients. In 2019 we began to work with ISA, a port logistics company, to improve its monitoring, management, and reporting processes, using agile methodologies.
We started the project with a Discovery stage that consisted of a series of meetings with the Product Owner and with the end-users. This stage allowed us to begin to get to know in-depth the problems and specific needs of the different Stakeholders. The client was a participant at all times in the creation process.
The work continued with the delivery of different instances of prototypes and MVPs, followed in all cases by customer feedback. This methodology, based on Scrum, allowed us to continue perfecting the final version. The finished product was a system, in mobile application format, that allows users to carry out a comprehensive tracking of all the ship’s tasks during service.
The added value of the Scrum methodology, as you can see with this real case, is to always have the customer’s vision and then have the tools to carry out an iterative process. This way we manage to optimize development costs, shorten times, and achieve a much better result!
Are you interested in knowing some of the Hybrid Mobile App Development Frameworks? Here we are going to tell you about some of the resources you will need for your future developments, to make your work much simpler and more efficient.
What are the Best Hybrid Mobile App Development Frameworks?
First of all, what exactly is a framework? According to ToolBox, it is a development framework that allows for solving complex problems in software development. In other words, a framework includes a set of tools, materials, or components useful for improving code work.
Do you want to know which are the most useful for hybrid development? Here are the most outstanding ones:
Xamarin allows developers to access the APIs, IDE, and language from anywhere. Through the use of C# code, developers can create a native app on different platforms. Therefore, from Xamarin, an application can be created much more efficiently.
That is, in Xamarin you will find different resources to work faster. For employers, this means greater profitability, as developers can have advanced features in one place, such as application debugging or code completion.
It should be noted that, for some time, Xamarin was too expensive to license. However, it was bought by Microsoft and became free. In this way, it came to have a very large community of developers, who help each other completely to contribute new resources.
Another one of the best frameworks. According to Netguru, it is a framework that can be used for both iOS and Android. Although it is also used to develop native apps, the truth is that there are many cross-platform functions so that hybrid applications can have the appearance and functionality of a native one.
One of the strongest points of React Native is that it is a community-driven framework. That is, as it is open-source, it is common to find new resources all the time to improve your developments. In addition, the quality of the developments is always guaranteed, since the application remains stable.
Another strength of this framework is that it has a good debugging process. A React Native app does not require a recompile to test every change, unlike the native app. Thus, the developer only needs to update the application in a simulator to observe the changes.
A final highlight is that React Native updates are faster and easier to maintain. In native applications, updating can be complicated, since each platform has a unique code. Instead, here you can do it simultaneously on each platform, reducing development times.
One of the main advantages is that in PhoneGap you will only write the application code once, thanks to HTML5 technology. Consequently, you will be able to publish it on any recognized mobile platform. In other words, it is one of the most valuable frameworks for saving development time.
However, it should be noted that PhoneGap is suitable only for those who know HTML5. In addition, the application will require a lot of processing and is not suitable for some applications, such as video games. On the other hand, it is ideal for those who are looking for fast development.
It is very useful to integrate with other frameworks recognized in the frontend field, such as Angular or Vue. Created in 2013, it offers a clean and functional design. In addition, it uses Capacitator to deploy natively, but it can also run in a browser as a progressive web app.
It is also one of the best options for those who are starting in the world of hybrid apps. Mainly because it has a user interface based on cards, lists, and tabs so that the information is well grouped and you can make integrations and plugins.
Therefore, all these resources will help you in your future developments. It doesn’t matter if you are an experienced programmer or if you are just starting: help is always welcome.
In short, you have learned about the best Mobile App Development Frameworks. You can take advantage of some of these resources for your next developments, generating better work in less time.
