Basic steps to create Reactive forms and Form Validation:

Know about Angular Forms:

Angular forms are used to deal with user inputs. It can include a massive no of input fields, spanning more than one tab. Forms may include complicated validation logic interdependent on multiple fields.

Some things forms are anticipated to do

  • Initialize the forms fields and gift them to the user
  • Collect the user information
  • Track adjustments made to the fields
  • Validate the inputs
  • Display useful errors(mistakes) to the user

Angular forms module offers all the above services. It binds the form field values to the Angular component class. It tracks adjustments made to the form fields in order that we can respond accordingly. The Angular forms will provide the built-in validators to validate the inputs.

Multiple approaches in angular forms creation:

There are 2 approaches to dealing with user input through forms:

  • Reactive forms
  • Template-driven forms

Reactive Forms approach

In Reactive Forms or Model-driven approaches, the logic of the form is described in the component as an object. The Model-driven approach has extra blessings as it makes the testing of the component easier.

Template-driven forms approach

In Template-driven approach is the simplest way to build the Angular forms. Template contains the logic of the form.

Steps to create Reactive Forms and custom validator:

Angular reactive forms follow a model-driven approach to handle form input whose values may be modified over time. These are also referred to as model-driven forms. In component class we can define the structure of the form. We can create the form model with Form Groups, Form Controls, and Form Arrays. We can create and update multiple form controls and define the validation rules in the component class. Create the HTML Form resembling the Form Model and bind the HTML Form to the Form Model.

1. Register the reactive forms module

You have to import ReactiveFormsModule from the @angular/forms package and add it to NgModule’s imports array to use reactive forms.

2. Generate and Import a new form control

First step: Generate a component for the control by running the following command:

ng generate component create-edit-person-form

The FormControl class is the fundamental constructing block used in reactive forms. To create and use a form control, you have to import the FormControl class into your component. Create a new instance of this form control to save it as a class property.

Write the following code in create-edit-person-form.component.ts file:

3. Now, register the control in the HTML form

After creating the control in the component class, you have to add it to the form control element in the HTML form template. Following is a regular HTML form which is enclosed with

tag. The template can be updated using formControl binding.

We have registered the form controls that are declared in .ts file to the input elements in the HTML template. Now, the form control and DOM element communicate with each other, and the view reflects changes in the model, and vice versa.

Create the validation service:

Run below command to create a new service:

ng g s servicescustomvalidation

This command will create a folder. Open the customvalidation.service.ts file and put the following code in it:

The PasswordPatternValidator method is used to validate the password pattern in our form.

Regular expression is used to validate the password and if the check fails, the invalidPassword property is to true.


This explains simple steps to create an angular reactive form and how to validate form inputs. The reactive forms are more flexible and handles complex scenarios. Reactive form module allows us to build the form model and offers an easy way to use reactive patterns and validations. And there are some extra benefits when you can do this when compared to template forms like easier unit testing.

We have used some of the built-in validators like email and required. There are many more built-in angular form validators like minLength, maxLength, pattern, etc.

We also can easily add custom validation on single fields as well as multiple fields combined in the form. Reactive forms are a little bit of a change from traditional template-driven forms, but there are some distinct benefits to using them.

Software as a Service (SaaS) refers to a unique software licensing model that has become hugely popular recently. If you remember well, once upon a time, we used to buy software packaged in a CD from the local electronics store. Those days are gone simply because software is now available over the air or the internet. Now software is offered to you with a subscription model, and the developer company takes full responsibility for maintenance and updates. This is what Software as a Service (SaaS) is all about. There are several reasons behind the popularity of the SaaS model of software development. What makes SaaS software so popular? The software as a Service (SaaS) model refers to cloud-hosted software delivered more as an internet-based service than a locally installed software. Some of the key advantages of this cloud-hosted SaaS software include the following. Cost competitive: With the cloud-hosted SaaS, you only need to pay for the resources used instead of purchasing software…

Naaldwijk, The Netherlands – Greenhouse Datacenters, a European data center developer/operator with two energy efficient colocation facilities in Naaldwijk, the Netherlands, in the Rotterdam/The Hague area, has opened a new data room in its flagship data center, Greenhouse DC 2. The expansion means a doubling of the current capacity at this location. At the same time, Greenhouse announces the appointment of Guido Sip as Chief Commercial Officer. In his new role, he will lead the commercial organization of Greenhouse and while further developing the company’s ecosystem of colocation partners and customers.

A stone’s throw from Rotterdam and The Hague, amidst the world’s largest flower and plant exporters and the many greenhouses in ‘the Westland’ region in the Netherlands, Greenhouse Datacenters offers colocation services that are ecologically oriented. The Power Usage Effectiveness (PUE) value of 1.2 achieved by Greenhouse is a very energy-efficient value. In addition, its two data centers are periodically audited and certified by independent auditors in accordance with the ISO 14001 standard (environment & sustainability).

With the opening of the newest data room in Greenhouse DC 2, Greenhouse Datacenters is now adding 400 square meters of colocation space to its flagship data center in the Netherlands. This represents an additional capacity of 260 data center racks. It also doubles the technical infrastructure of Greenhouse DC 2 including generators, indirect adiabatic ‘Fresh Air’ cooling and energy efficient UPS systems.

Guido Sip as CCO, Customer Growth

Greenhouse Datacenters has grown rapidly in recent times. Two data rooms are now in use in Greenhouse DC 1. The newest operational room in Greenhouse DC 2 is the fourth data room that has been delivered. The first customers are now moving their IT infrastructures into this new colocation area. To secure further growth opportunities for its colocation customers, strategic plans for the construction of Greenhouse DC 3 – in the immediate vicinity of the current two data centers in the Netherlands – are already underway.

Guido Sip has been hired as Chief Commercial Officer (CCO) to manage the current expansion and further shape the commercial organization of Greenhouse. He comes from fiber network provider Relined, where he had been working for 7 years in total. The last 4 years he held the position of Director Sales and Marketing. In this role he was part of the four-person management team of Relined.

“Greenhouse has grown particularly rapidly in the last few years. Without a significant focus on sales though, and mainly based on delivering technical and process-based quality at a competitive price,” says Guido Sip, Greenhouse’s newly recruited CCO. “My goal now is to build a solid sales strategy and enhance market visibility worldwide for the high-quality colocation services that Greenhouse offers from the Netherlands. Success until now is primarily the result of this typical ‘Westland’ mentality, in which a lot of value for money is being offered and the colocation services are actually selling themselves. The next step is to maintain that Westland mentality while professionalizing sales and further shaping the partner and customer ecosystem. My experience as board member at Relined will certainly help. My personal network in the industry is quite large and I bring extensive experience to the table with building partner ecosystems and achieving business expansion.”

In his previous role as a board member of Relined, Sip experienced strong growth of the organization. It included a doubling of the number of clients among which hyperscalers; an expansion of the fiber network from 5.000 to 28.000KM; as well as strong expansion of Relined in Germany.

Satellite Dish Services

With Guido Sip in the newly created position of Chief Commercial Officer, Greenhouse Datacenters expects to further raise interest in its ecological colocation services and its focus on security, connectivity, cloud-enablement, compliance, scalability and 24/7 rapid on-site support. Greenhouse’s management team also sees enormous customer potential in the Rotterdam and The Hague region. Especially because of the company’s satellite dish farm onsite and its 10 Gigabit low latency radio links through which companies throughout the area can easily access the Greenhouse data centers – for backup, archiving, disaster recovery, and more.

“I know Guido from his former job role as a board member of Relined. The responsibilities connected to his previous position are illustrative of the next steps we want to take with Greenhouse,” says Lennert Vollebregt, co-founder of Greenhouse Datacenters. “We expect a lot from Guido, also considering what he has achieved at Relined in a relatively short period of time. He is an outgoing personality focused on networking and has a good view on ecosystem thinking and the creation of partner opportunities. The health risks we are now facing worldwide are of course limiting current networking options, but as soon as this has become somewhat normalized, we will be able to further increase our visibility in the market with Guido as our CCO.”

WAYNE, PA – Sungard Availability Services (Sungard AS) has expanded its Payment Card Industry Data Security Standard (PCI DSS) certification across its modern, resilient cloud platforms, and now offers compliant production and disaster recovery services on Amazon Web Services (AWS) and its managed private cloud.

Organizations are often burdened with achieving PCI DSS compliance for everything from their infrastructure to their applications. By achieving certification, Sungard AS now reduces the complexity and cost of the process for customers, who only need to certify their applications.

While initial certification takes months or even years and can be costly, the real challenge for many organizations is maintaining it. One study from Verizon’s PCI DSS Compliance report found that only 29 percent of organizations were still compliant a year after their initial certification. Sungard AS is among those few, having demonstrated its ability to maintain PCI compliance for other services for half a decade, assuring that it can enable compliance for all customers.

“We’re continually updating and improving our cloud offerings to keep pace with market changes as well as deliver the service customers need,” said Josh Crowe, Chief Technology Officer at Sungard AS. “By certifying our cloud platforms for PCI compliance, customers who need PCI compliance can leverage our AWS and managed private cloud services to achieve their objectives quickly for both production and recovery workloads.”

AWS shared responsibility model of security means that while AWS is PCI-compliant, the elements organizations add to the cloud, from their operating systems, network and firewall configuration to their client-side and server-side data protections, must be PCI-certified by each organization. Sungard AS offers both production and recovery environments that are PCI-certified, saving crucial steps.

Private clouds grant organizations more control for mission-critical or complex workloads, achieving agility, security and economics with platforms like VMware. But the PCI certification process can be arduous in private cloud because both production and recovery environments must be compliant. Sungard AS uses the exact same infrastructure for production and recovery in a hosted private cloud, which both eliminates the double work and speeds PCI-compliant recovery.
