5 Outline What is Software Architecture & Why is It Important? Key Facets of Cloud Computing & Architecture Systematically Building Architectural Knowledge for Cloud-Based Systems Cases of Leveraging Architectural Knowledge Concluding Remarks

6 Why is Architecture Critical & What is It?

7 Some Scenarios for Architectural Support legal experts Scenario 3 data only in region B processing only in region A Region B specification tools Scenario 2 data only in region B domain experts Scenario 1 processing and data only in region A Region C Region A A Public Agency Wants to Use Clouds for Storing and Processing Highly Sensitive Data. An Engineering Company Intends to Use Clouds for its Highly Confidential Documents. Leveraging Cloud Bursting without Violating Legal Constraints and Agreements with Customers

8 Software Architecture The software architecture of a system is the set of structures needed to reason about the system, which comprise software elements, relations among them, and properties of both (Bass, L., et. al., 2013). Fundamental concepts or properties of a system in its environment embodied in its elements, relationships, and in the principles of its design and evolution (ISO/IEC 42010). Its all about DECISIONS in certain context bad, good and better ones.

9 Relating Architecture with Cloud Computing Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. (A definition by the US National institute of standards and technology (NIST))

10 Key Facets of Cloud Computing & Architecture Reproduced from Figure 1 of The Future of Cloud Computing: Opportunities for European Cloud Computing beyond 2010.

11 Getting Architecture Right is Hard!..The life of a software architect is a long (and sometimes painful) succession of sub-optimal decisions made partly in the dark (Philippe Kruchten)

12 Knowledge Centric Design & Evaluation Specifying ASRs Patterns and tactics Sketches of candidate views, Determined by patterns Chosen, combined views plus doc n. beyond views text text text Architecture design Prioritized Quality Attribute Scenarios Documenting Architecture Evaluation Requirements, constraints Stakeholders Adapted from: Hofmeister, C., et al., A general model of software architecture design derived from five industrial approaches. Journal of Systems and Software 80(1): (2007).

13 Systematically Exploring Relevant Literature

14 Empirism as a Research Approach Empiricism Generally being regarded at the heart of the modern scientific methods, that our theories should be based on our observations of the world rather than on intuition or faith Empirical Software Engineering (ESE) Empirical research in SE is the scientific use of quantitative and qualitative data to understand and improve software product and software development process (Vic Basili) Data is central element to address a research issues related to processes, technologies, or people ESE Helps in Understanding and Developing/ Improving Processes, Technologies, People

15 Key Areas of Architectural Research Challenges

16 Research Challenges for Architectural Support Interoperability Support for interoperability for multiple collaborative services. Privacy Identifying trusted cloud services to process sensitive data. Data placement strategies based on privacy requirements. Scalability Automatic identification of traffic patterns for dynamic scalability. Adaptability Support adaptability of service transmission environment according to specific Quality of Service (QoS) requirements and provide communication space specific to a customer s needs. Service Selection Collaboration among cloud service providers (service discovery, advertisement and composition). Market-oriented resource and service provisioning.

17 Research Challenges for Architectural Support Cloud Service Federation Cloud brokerage for federated clouds. Increase capacity by delegating tasks to federated clouds. Inter layer mappings of corresponding layers of reference cloud mode among federated clouds. Decentralize deployment infrastructure of by multiple providers. Limited resource in a single cloud provider in stressed data centers. Avoid cloud vendor lock-in. Service Level Agreement (SLA) Compliance SLA specific cloud services discovery. Cloud system behavior anticipation according to specific QoS requirements. Decentralization of consistency and scalability management of the services.

18 Research Challenges for Architectural Support Pervasive Embedded Networks on Cloud Management of mash-up services on shared cloud resources. Compliance with concrete semantic structures for information presentation and communication. Domain Specific Data visualization from various types of data sources (wireless devices, web applications and medical images). Workflows management on cloud Business processes cooperation for processing sensitive data. Rationally fragmenting a workflow model. Deploy workflow fragments on the underlying collaborative architectural components.

19 Building and Leveraging Body of Knowledge

20 Design Knowledge Support Architectural Knowledge Share (C) Lack of Architectural Knowledge usually Results in Severe System Design Problems. Huge Technical Debt on Suboptimal Design Decisions. General Knowledge Context Knowledge Integrate (B) Distill (H) Apply (I) Trace (D) Trace (D) Learn (E) Producer Architect (A) Reasoning Knowledge Consumer Evaluate (F) Synthesize (G) Trace (D) Search / Retrieve (J) Evaluate (F) Design Knowledge Key Guidance and Tools Knowledge Type Actor Traceability created by producers and used by consumers Consuming activity Producing activity Types of Architectural Knowledge. Manage & Share Knowledge. Architectural Description for Reuse. We Developed A Characterization Scheme of Architectural Design Knowledge. An Infrastructure for Capturing and Sharing Architectural Knowledge.

38 Quality Attributes & Architectural Decisions Quality Attributes Scalability Portability Compatibility Reliability & Autonomous Scalability Efficient & effective deployments Architectural Decisions Amazon EC2 & S3 Google App Engine Replication of system services to meet performance requirments. Separation of database layer into a new service that utilizes platform specific persistency features. A wrapper layer is added to ensure platform independence. A separate database layer to provide seamless transfer of database layer. System features are exposed through origonal REST API. A wrapper layer is added to provide abstraction to services cluster and their deployment configuration. Façade/Waper layer to provide abstraction. Amazon s Elastic Load Balancer ensures autonomous scalability. Amazon Elastic Load Balancer ensures auto scaling as well as efficient and cost effective deployment configuration. No action required. Scalability is handled by platform. Refactoring of persistency components to make it compatible with Google Datastore persistence. Portability to other platforms is not possible. System features are exposed through origonal REST API. Ensured by platform. Deployment of application components on cloud is managed by platform.
