Evolving Systems Explain What is containerization and why does it matter?

        

One of the software trends that’s emerged over the past couple of years, Containerization, has quickly picked up pace, building on the momentum of another trend, virtualization, which it can either replace of complement.

Containerization is the ring-fencing and packaging of an application so that can run across any infrastructure. This affords benefits to developers, ops teams, and overall infrastructure alike.

For developers, Containerization enables applications to be deployed quickly and securely. An alternative to traditional practices in which code is built in a specific environment and then transferred to a new location, often resulting in bugs and errors, Containerization bundles application code with its related configuration files, libraries, and dependencies. The resulting package or “container” is free standing and portable - able to run across any platform or cloud.

What we’re really talking about here is process isolation and that’s not new. However, the development of an open source engine, Docker, which delivers an industry standard for containers has accelerated the popularity of the Container approach. Leading analyst firm gartner predicts that over 50% of enterprises will use container technology this year.

Containing Applications

Where applications are concerned, Containers encapsulate the software as a single executable package that, as noted above, bundles application code with all of its required configuration files, libraries, and dependencies. This means simple, fast, deployment Isolated from its environment, the containerized application is not reliant on a copy of the operating system but rather, an open source runtime engine (for instance, Docker) is installed on the host’s operating system and acts as a bridge for the contained application to function with other containers on the same computing system. Quite apart from efficiency, application isolation of applications reduces the risk that malicious code present in one container will invade the host system.

The abstraction of the containerized application enables portability and consistency of operation across any or cloud. Containers can be easily transported from a desktop computer to a virtual machine (VM) or from a Linux to a Windows operating system, which means that software developers can use whichever tools and processes play to their strengths.

Everyone Wins

To summarise, containerization delivers measurable benefits to developers and development teams:

Portability

Agility

Speed

Fault isolation

Efficiency

Ease of management

Security

These benefits are critical in a communications landscape that is rapidly moving to the cloud and where it’s critical that users have the ability to develop applications quickly and efficiently. Containers (along with other trends including micro-services and cloud computing itself work with each other to deliver application development and deployment benefits that traditional methodologies and environments do not support. Next-generation architectures have to be agile, efficient, reliable, and secure to, ultimately, meet the needs of end users and the market. Containerisation is likely here to stay.

Innovative customer engagement gives people what they want. The questions is, what do subscribers want?

Digitization, it’s no secret, is changing the landscape for Communications Service Provides . Not before time. In the telecommunications industry new subscriber growth has slowed and profits have slowly been eroded as a result of price wars that more often than not end up in the self-destructive commoditization of services. Monthly ARPU goes down at the same time that the cost to serve and consumer demand for connectivity speeds and volume of data consumption goes up.  For the CSP, that’s not a sustainable position . As a result, this reality is clear: No longer can the telecommunication  industry treat or charge customers as they have done historically, at the SIM card level. Today, CSPs must innovate and engage customers at a household level if they want to ensure future profitability. To do this, innovative approaches to C ustomer Engagement  are critical.

Remote SIM Provisioning and Activate, Engage & Retain Customers on Digital Stage : Evolving Solutions

Image
A ctivating  SIMs: H ere’s   The Standard Evolving Systems’ innovative and patented Remote S IM  Provisioning  solution represents the new standard for activating SIM cards. It’s available as a SaaS (Software as a Service) solution or it can be deployed on premise and it allows Communications Service Providers to offer the user experience and resource efficiency benefits of provisioning at point of sale without the retailer or subscriber self-service infrastructure costs. In other words, it delivers a significant advantage. Deploying DSA means SIM cards can be activated the moment that a phone is first switched on and used. The need for any extended interaction with the wireless operator is thereby removed. Everything necessary is via done the handset in the palm of the customer’s hand. With DSA, operators can sell any product in any channel. They benefit from being able to deliver unprecedented scope for personalization at the point of first use, and greater engagement with their exis
