through Modularity with Episerver Hi! Im Casper Rasmussen [ smusn] - PowerPoint PPT Presentation

Ascend Embrace Business Changes through Modularity with Episerver

Hi! I’m Casper Rasmussen [ ˈʁɑ smusn]

Agenda 1. Let’s build a business case The benefits of software sustainability 2. Theory behind Let’s talk about Absorb evolution and adapt to change via a modular programming manifesto software 3. How we put this to life with Episerver What does Episerver bring and let’s see how it can look Episerver

Sustainable software is everyone’s goal – Create organizational efficiencies – Lower the total cost of ownership of software over time – Stabilize the larger IT eco-system Episerver

Our Business Case Ensure the investment in new software brings a long lasting digital asset Episerver

How to meet this objective? Rely on the theoretical principles in existing software methodologies as levers for the heavy lifting Episerver

Enable Sustainability Sustainable software has a greater capacity to endure Factors to a sustainable software investment – Maintainability – Scalability – Documentation – Reliability – Adaptability – .. Episerver

Adapt to change External influences Adaptability is the extent to which a software system adapts to change in its surroundings. Measures – Integration layers – Redundancy – Communication protocols – Backward compatibility – Portable application stack Episerver

Adapt to change It’s more than that.. Self-adaptable software absorbs evolution caused by changes coming from within Measures – Separation of concerns – Dependency inversion – Strict use of code contracts – Access modifiers Episerver

Raise your hand Let me understand your experience with those measures Episerver

How to create self- adaptable software The modular programming manifesto The final product should be assembled from independently developed modules. Benefits – Be in control of evolving complexity – Reduces impact caused by interconnected code – Efficient development – Mitigates the entropy of software Episerver

Modules are the pieces creating your software. Episerver assembles them to a working system. Episerver

Episerver and modularity Utilize Episerver’s architecture to build a solution that absorbs change Episerver

Episerver is the orchestrator Acting as the glue Episerver retains the integrity of the modular system at runtime. Platform responsibility – Registration, initialization and dynamic loading of platform modules – Management of module interdependencies – Routing – Foundational modular framework – .. and of course enterprise content management and commerce features Episerver

Episerver is already a modular framework Episerver has a modular mindset Let’s benefit from the approach native features, such as Episerver Find, already relies on. What’s for instance in the Episerver toolbox – Initialization mechanism – Assembly scanning providing automated registration of e.g. content types or plugins – Inversion of control and Dependency inversion through StructureMap – Content and template routing Episerver

Good practices Code Process – Define clear contracts to describe the responsibility of – Validate module dependencies during your code your module reviews – Avoid unwanted module dependencies – always ask – Sketch early – identify modules and yourself: should a change to this dependency affect my interdependencies when defining your solution module? architecture – Use access modifiers to hide all code that’s considered – Avoid sporadic identification of new modules implementation without architectural consent – Never rely on implementations within dependent modules – Document to keep architecture and purpose of – they may change! platform consistent over time – Avoid breaking contracts in your module - it will break dependencies! – Avoid replacing Episerver implementations. It may lead to unwanted issues. Episerver
