Cloud: PaaS – platform as a service

The abbreviation PaaS , short for Platform as a Service , describes the middle tier of the cloud service models. The main benefit is, in particular, the simplification of the development and provision of applications as well as greater efficiency. Here the user has to take the software development into their own hands. At the same time, however, this also means for him that PaaS already brings elements such as runtime environment or operating system with it. Nevertheless, all important responsibilities are borne by the provider. Advantages and disadvantages of PaaS At the same time, there are also some noteworthy advantages and disadvantages with this service model. With PaaS, these parameters stand out in particular: benefits faster and less complicated development and delivery of the softwareDevelopment, test phases and operation possible on a uniform platformSoftware development lifecycle easy to manageMany functionalities are directly available, e.g. authentication, security features, database management…

Tips for writing good texts

I wrote a lot of text during my doctorate and texts are very important, especially in an academic context. In the following I have summarized my findings from 5 years of doctorate. It may help one or the other. language It is our ability to generate and understand language that makes us special. Our perception in society also determines our language. Of course, other forms of life such as animals also coordinate with each other, but this language is used more for mere information and is nowhere near as deep and complex as human language. Reading tip: Meaning of language Language can arouse emotions and control the reader’s impression of the text. From open to populist – anything is possible. My findings are: Avoid superlatives and unambiguous statements (all companies)Use open languageAvoid causal relationshipsIntroduction of clear terms, subsequent definition and permanent use of the uniform termPut terms in the right…

Cloud: SaaS – Software as a Service

With SaaS , short for Software as a service , the third service model of clouds is now described at this point. Applications can be used directly via the Internet or via the browser. By purchasing licenses (mostly in the form of subscriptions) to use the service via the web browser, the user only has to log into the web application with his login data. Installation on your own internet-enabled device and the purchase of additional hardware with increased computing power are no longer necessary. And the user does not have to back up data and install current updates himself, as these tasks are taken over by the cloud provider himself. At the same time, this means that companies usually have to pay a monthly or annual fee for use, based on the number of users. SaaS is available in many areas. These include, for example: e-mailOffice and writing programsCustomer…

Manager in tunnel vision: change after 5 years

In ophthalmology, tunnel vision stands for a concentric narrowing of the field of vision to a central remainder ( Wikipedia ). You will surely notice that yourself: as soon as you do something for a while, you get the famous tunnel vision and lose sight to the left and right. Our body switches to such tunnel vision in 2 situations. On the one hand, as soon as the body isolates itself from other influences and stimuli in order to protect itself and on the other hand, after a while in a project, you cannot see the forest for the trees. The view is only just about. Problem: The tunnel view for managers You know it: you suggest a tip to managers, but they don’t listen to it. The head of department, who has been in charge of the department for many years, has run the risk of tunnel vision for…

Cloud: The hybrid cloud

With the Hybrid cloud is the name given to the interaction of the two variants of public and private cloud. The hybrid cloud thus corresponds to a services environment consisting of private cloud services and public cloud services. It therefore combines the advantages of both types of cloud. In addition, the three models IaaS, PaaS and SaaS can be used within the hybrid cloud (see Fig. 1). Private cloud vs. public cloud To understand how exactly the hybrid cloud works, it is first necessary to know the characteristics of its basic components. Private cloud (own server) Focus on securityfull possibility of customizationown control Public cloud (server of one provider) low costPossibility of flexible billinghigh scalability Building the hybrid cloud For medium-sized and large companies, it is often sensible to combine both types of cloud in the form of a hybrid cloud in view of the low costs and high scalability…

How does the collaboration of remote teams work through processes and tools?

I have been working with virtual teams for more than three years and keep building them up. Companies are often still organized in the classic way and start with the first virtual teams due to multiple locations and a shortage of skilled workers. This makes sense because, in addition to location advantages (customers, resources), skilled workers can also be employed in each region. In this article I would like to show my experiences, which are important for setting up such virtual teams and what exactly the specific differences to local teams are. Virtual teams mean that you have to work with tools. Tools like the phone, email, and video conferencing. Whatever it is, it is a different type of work and we are still in the process of fully understanding it.Member of the executive board of an IT service provider in Round table Represent work in a meaningful way, virtually…

How can you implement the Spotify model in traditional companies?

Companies have always been in constant change. Be it in terms of technology or organization. Now that agile methods have found their way into companies, the credo is now to synchronize various agile and classic methods and to break up classic hierarchies in order to make your own organization faster and more flexible. One approach to this can be the Spotify model, which has been gaining more and more importance since 2014. But German companies are characterized by special processes and a long tradition – in contrast to Spotify, which started out on the greenfield. So is it possible to just copy the Spotify model? Certainly not! In this article, I would like to show my experience in introducing and adapting the Spotify model for a fictional German company and underpin it with my experience of the last 2 years from my professional experience with the Spotify model. For general…

Basics of cloud technologies

The beginnings of cloud technologies go back almost 20 years. Even after the turn of the millennium, large companies such as Amazon, Google, IBM, Yahoo and Co were experimenting with the flexible use of computers over the Internet. At the moment, the focus was primarily on the increasing user base at peak times such as Christmas. Companies such as the online retailer Amazon are striving to serve their customers faster and more efficiently through bundled computers via the Internet. From these beginnings, today’s cloud technologies finally developed. But what exactly do they actually describe? What service and delivery models for cloud technologies are there now? And what conclusions can be drawn from the rapid development? What does the term mean? The use of special IT infrastructure is described with the term “cloud”, in English “cloud”. It is primarily a matter of making IT resources available dynamically via the Internet in…

Cloud: IaaS – Infrastructure as a Service

At IaaS , short for Infrastracture as a Service , is a service model of cloud technologies. The user can manage the environment himself, apart from the physical infrastructure. IaaS also offers the advantage that it is comparatively inexpensive by sharing resources with other users. In addition, this service model is structured in such a way that several servers are provided in a network in a data center, which together form a cloud. In other words, the hardware is virtualized and thus enables companies to keep their financial expenses in the cloud area low. Packages from IaaS The resources linked to this system are usually made available in a kind of smaller package. These in turn contain individual components such as: Virtual CPUs: Virtual CPUs differ from real CPUs in that no dedicated CPUs are provided for a customer, but the calculations are carried out on currently “free” cores.Storage: Typically…

Interface between sales and IT – customer management #agilerVertrieb

You all know it: trench warfare between sales and IT. They can cost businesses a lot of money and are often nerve-wracking. The problems are obvious: While sales based on commissions are more aimed at closing sales (quantity), IT is careful to build high-quality systems. You can imagine that friction is inevitable. In this article I use exaggerated metaphors to better show the scenario. Agility in sales is not a solution #agile sales One solution can be that you simply want to use agile methods in sales. I’ve been called a lot lately and asked how to set up agile sales. I hear sentences from managers like: “Our sales department should become more agile” and from clueless salespeople: “Well, we’re trying to do that with the sprints, but somehow that doesn’t bring us anything”. The perplexed salespeople are absolutely right in my opinion. A salesperson is inherently agile because he…
