Lift n Shift Approach to Cloud Transformation

What does it mean to Rehost an application?

Rehosting is an approach to migrating business applications hosted in on-premises data center environments to the cloud by moving the application “as-is,” with little to no changes to the business functions performed by the application. It’s a faster, less resource-intensive migration approach that gets your apps into the cloud without much code modification. It is often a good first step to cloud transformation.

Organizations with applications that were initially developed for an on-premises environment commonly look to rehosting to take advantage of cloud computing benefits. These benefits may include increased availability and networking speeds, reduced technical debt, and a pay-per-usage cost structure. When defining your cloud migration strategy, it’s essential to analyze all migration approaches, such as re-platforming, refactoring, replacing, and retiring.

SPFx Modern Web Development

SharePoint has been a widely adopted and popular content management system for many large organizations over the past two decades. From SharePoint Portal Server in 2001 to SharePoint Server 2019 and SharePoint Online, the ability to customize the user experience (UX) has evolved dramatically, keeping pace with the evolution of modern web design. SharePoint Framework (SPFx) is a page and web part model that provides full support of client-side SharePoint development with support for open sources. SPFx works in SharePoint Online, and with on-premises SharePoint 2016, and SharePoint 2019. SPFx works both in modern and classic pages. SPFx Web Parts and Extensions are the latest powerful tool we can use to deliver great UX!

Advantages of using SharePoint Framework

1. It Can’t Harm the Farm

Earlier SharePoint (SP) customization code executed on the server from compiled, server-side code is written in a language such as C#. Historically, we created web parts as full trust C# assemblies that were installed on the SharePoint servers and had access to disrupt SharePoint for all users. Because it ran with far greater permissions on the server, it could adversely impact or even crash the entire farm. Microsoft tried to solve this problem in SP 2010 by implementing Sandbox solutions, followed by the App Model, now known as Add-In model.

SPFx development is based on JavaScript running in a browser, making REST API calls to the SharePoint and Office 365 back-end workloads and does not touch the internals of SharePoint.

The SharePoint Framework is a safer, lower-risk model for SharePoint development.

2. Modern Development Tools

Building SPFx elements using JavaScript and its wealth of libraries, the UX and UI can be shaped as beautifully as any modern website. The JavaScript is embedded directly to the page, and the controls are rendered in the normal page DOM.

SharePoint Framework development is JavaScript framework-agnostic. The toolchain is based on common open-source client development tools such as npm, TypeScript, Yeoman, webpack, and gulp. It supports open-source JavaScript libraries such as Node.js, React.js, Angular.js, Handlebars, Knockout, and more. These provide a lightweight and rapid user experience.

3. Mobile-First Design

“Mobile first”, as the name suggests, means that we start the product design from the mobile end, which has more restrictions to make the content usable in the small space of a phone. Next, we can expand those features to a more luxurious space to create a tablet or desktop version.

Because SharePoint Framework customizations run in the context of the current page (and not in an IFRAME), they are responsive, lightweight, accessible, and mobile-friendly. Mobile support is built-in from the start. Content reflows across device sizes and pages are fast and fluid.

4. Simplified Deployment

There is some work to do at the beginning of a new project to set up the SPFx structure to support reading from a remote host. An App Catalog must be created, as well as generating and uploading a manifest file. If the hosted content is connected with a CDN (Content Delivery Network), that will also require setup. However, once those structural pieces are in place, deployment is simplified to updating files on the host location. It does not require traditional code deployments of server-side code, with its attendant restrictions and security review lead time.

5. Easier Integration of External Data Sources

With SPFx, calls to data from external sources may be easier since it’s web content hosted outside of SharePoint.

SPFx Constraints and Disadvantages

The SharePoint Framework is only available in SharePoint Online,  on-premises SharePoint 2016, and SharePoint 2019 at the time of this blog. SPFx cannot be added to earlier versions of SharePoint such as SharePoint 2013 and 2010.

SharePoint Framework Extensions cannot be used in on-premises SharePoint 2016 but only in SharePoint 2019 and SharePoint Online.

SPFx, like any other client-side implementation, runs in the context of the logged-in user. The permissions cannot be elevated to impersonate as an admin user like in farm solutions, CSOM (client-side object model) context, or in SharePoint Add-ins and Office 365 web applications. The SharePoint application functionality is limited to the current user’s permission level, and customization is based on that as well. To overcome this constraint, a hybrid solution implementation with SPFx to communicate with Application Programming Interfaces (APIs). APIs would be registered as SharePoint add-in, that uses the app-only context to communicate with SharePoint. For this communication between SPFx and API to work, the API would need to support CORS (Cross-Origin Resource Sharing) as the communication would be through cross-domain client-side calls.

SPFx is also not for long-running operations as it is entirely client-side implementation. The web request cannot wait longer until it gets the response from the long-running web operation. Hence for those processes, the hybrid approach with long operations can be implemented in Azure web job/function, and SPFx can get the update from those via webhook.

Developers coming from server-side will have a learning curve with entirely client-side development. But TypeScript is there for the rescue.

SPFx Comparison to Other Technologies and Models

SharePoint lists come in handy for many organizations when entering data, but customers always ask for the ability to display the data in some reporting format, such as a dashboard. Below we compare the different ways we can accomplish this and why SPFx is a good fit:

  • Classic Web Part Pages: If we do not want to use the SharePoint Framework, SharePoint 2019 still supports the classic web part pages. You can add content editor web parts and deploy any custom JavaScript/jQuery code. However, with this approach, uploading the Js files in the SP library and manually adding pages in a library become cumbersome. We may end up writing custom JSOM (JavaScript object model) code to make the deployment easier. Microsoft does not recommend this approach, and there is the possibility that this will no longer be supported in the future. Also, with this approach, if you want to render any custom tables, you need to write custom code or use a third-party table. Using SharePoint Framework, we can easily use Office UI Fabric React components like Details list.
  • Custom App: We can design custom applications to deploy in the cloud, which can read the data from SharePoint. The challenge is that each customer environment is different. It’s not always easy to connect to SharePoint from the cloud in a production environment, especially with CAC (Common Access Card) authenticated sites.
  • PowerApps/LogicApps: With newer technologies such as PowerApps, Logic Apps, and Flow, we can design custom SharePoint Forms and business logic and connect to SharePoint using the SharePoint connector. In a production environment, it is not easy to get connection approved and to connect with on-premises data. PowerApps and Flow require the purchase of licenses.

Using SPFx, we can quickly design the dashboards using Office UI Fabric components. For deployment, we do not need to write any custom utility code, SharePoint framework package can create the lists and libraries as well.

Wrapping Up

We hope this blog provided an SPFx overview and its great functionalities. Please look forward to our next blog post (Part II) in developing and deploying custom SPFx Web Parts, Extensions, and connecting to API’s/Azure in SharePoint Online and SharePoint 2019!

It can be challenging to maintain a repository after it’s been in use for months, through iterations, and by more and more teams. The online interfaces to team Git repositories – GitHub, Azure Repos, etc. – have several views into the current state of your repo.

  • Who last committed to that branch
  • How old is the branch
  • Quick buttons to delete stale branches

Even with these tools, it may not be easy to identify which branches truly require cleanup. In this article, we’ll explore how to use PowerShell to assist with targeting and operating on Git branches that meet the criteria we establish.

To demonstrate the commands being used, I use PowerShell from within a Jupyter notebook by running a container authored by GitHub user @jaykul – jaykul/powershell-notebook-base. The full exercise with code is hosted on Azure Notebooks. Azure Notebooks is a free hosted service to develop and run Jupyter notebooks in the cloud with no installation.

Conclusion

Commands in Git have options to format their output and produce data-rich textual output to the command line. PowerShell is an expressive shell language which allows quick sorting, filtering, and fluid operation on rich data types. Combining the two makes quick work of performing repository maintenance, producing reports, and integrating your repository with other tools.

Using calculated metrics like commits ahead or behind creates the ability to automate process rules you might implement with your team. With all the rich data available through Git, there are bound to be several devops workflows your team can automate with PowerShell.

Exchange 2010 is at the end of its journey, and what a long road it’s been! For many customers, it has been a workhorse product facilitating excellent communications with their employees. It’s sad to see the product go, but it’s time to look to the future, and the future is in the Microsoft Cloud with Exchange Online

What does End of Support mean for my organization?

email security exchange 2010 end of support risks

While Exchange 2010 isn’t necessarily vanishing from the messaging ecosystem, support of the product ends in all official capacities on January 14, 2020. Additionally, Office 2010 will be hitting the end of support on October 13, 2020, which means your old desktop clients will also be unsupported within the same year. What this means is that businesses using Exchange and Office applications will be left without support from Microsoft – paid or free. End of support also means the end of monthly security updates. Without regular security updates and patches from Microsoft to protect your environment, your company is at risk.

  1. Security risks – Malware protection and attack surface protection become more challenging as products are off lifecycle support. Any new vulnerability may not be disclosed or remediated.
  2. Compliance risks – As time goes on, organizations must adhere to new compliance requirements – for example, GDPR was a massive recent deadline. While managing these requirements on-premises is possible, it is often challenging and time-consuming. Office 365 offers improved compliance features for legal and regulatory requirements. The most notable is that Microsoft cloud environments comply with most regulatory needs, including HIPAA, FISMA, FedRAMP, and more.
  3. Lack of software and hardware support – Lack of technical support for problems that may occur such as bug fixes, stability and usability of the server, and time zone updates. Dropped support for interoperation with 3rd party vendors like MDM and message hygiene solutions can mean your end-user access can stop working. Not to mention the desktop and mobile mail solutions already deployed, or perhaps being upgraded, around this now decade-old infrastructure.
  4. Speaking of old infrastructure – This isn’t just about applications and services. For continued support and to meet compliance requirements, you must migrate to newer hardware to retain, store, and protect your mailbox and associated data. Office 365 absolves you of all infrastructure storage costs. That is a perfect opportunity, and often a justification in and of itself, to move to the cloud.

It’s time to migrate to Office 365 . . . Quickly!

There are many great reasons to move your exchange environment to a hosted environment in Office 365. The biggest one being your company will no longer have to worry about infrastructure costs.

Here are some other significant advantages that you won’t have to worry about:

  • Purchasing, and maintaining expensive storage and hardware infrastructure
  • Time spent keeping up to date on product, security, and time zone fixes
  • Time spent on security patching OS or updating firmware
  • Cost for licensing OS or Exchange Servers
  • Upgrading to a new version of exchange; you’re always on the latest version of Exchange in Office 365
  • Maintaining compliance and regulations for your infrastructure whether Industry, Regional or Government
  • With an environment of thousands of users and potentially unlimited mailboxes, absolving your admins from the day-to-day database, storage, server, and failover management is a huge relief and cost savings by having your team focus on Exchange administration.

Another big cost for on-premises is storage: data repositories for mailbox data retention, archiving, and journaling. This value cannot be overstated – do you have large mailboxes or archive mailboxes? Are you paying for an archiving or eDiscovery solution? If you consider Exchange Online Plan 2 licenses (often bundled into larger enterprise licenses such as E3 or E5) they allow for archive mailboxes of unlimited size. These licenses also offer eDiscovery and compliance options that meet the needs of complex organizations.

The value of the integrated cloud-based security and compliance resources in the Office 365 environment is immense. Many of our customers have abandoned their entire existing MDM solutions in favor of Intune. Data Loss Prevention allows you to protect your company data against exfiltration. Office 365 Advanced Threat Protection fortifies your environment against phishing attacks and offers zero-day attachment reviews. These technologies are just the tip of the iceberg and can either replace or augment an existing malware and hygiene strategy. And all these solutions specifically relate and interoperate with Exchange Online.
