Application Darwinism: Why Most Enterprise Apps Will Move to the Cloud (SVC20...Amazon Web Services
(Presented by Skytap) Complex multi-tier enterprise applications that have been under development for decades assume reliable hardware and typically have dependencies on underlying operating systems, hardware configurations, and network topologies. The boundary between one application or service and another is often fuzzy, with many interdependencies. These traits make some enterprise applications difficult to refactor and move to a public cloud. Even the teams that manage these applications can be unfamiliar with cloud terminology and concepts. In this session for enterprise IT architects and developers, Brad Schick, CTO of Skytap and Skytap customers Fulcrum, DataXu and F5 will share their insights into why the evolution of enterprise applications will lead to hybrid applications that opportunistically take advantage of cloud-based services. Brad will then demonstrate Skytap Cloud with Amazon Web Services and discuss how enterprises can easily achieve this integration today for application development and testing.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.

Cloud computing has emerged as a transformative force in the realm of information
technology, revolutionizing the way businesses and individuals access, store, and manage
data and applications. At its core, cloud computing offers on-demand access to a shared
pool of configurable computing resources, including networks, servers, storage,
applications, and services, delivered over the internet. This paradigm shift represents a
departure from traditional on-premises infrastructure models, offering unparalleled
scalability, flexibility, and cost-efficiency.
The advent of cloud computing has been driven by several technological advancements,
including the proliferation of high-speed internet connectivity, the commoditization of
hardware, and the development of virtualization and containerization technologies. These
innovations have democratized access to computing resources, enabling organizations of
all sizes to leverage the power of the cloud to accelerate innovation, drive digital
transformation, and gain a competitive edge in today's fast-paced business landscape.
One of the defining characteristics of cloud computing is its service-based delivery
model, which is typically categorized into three primary deployment models: public
cloud, private cloud, and hybrid cloud. Public cloud services are offered by third-party
providers on a pay-as-you-go basis, allowing organizations to access computing
resources and services from shared infrastructure hosted off-site. Private clouds, on the
other hand, are dedicated infrastructure environments that are provisioned and managed
for the exclusive use of a single organization, providing greater control and customization
options. Hybrid clouds combine elements of both public and private clouds, allowing
organizations to seamlessly integrate on-premises infrastructure with public cloud
services to meet specific business requirements.
Furthermore, cloud computing encompasses a wide range of service models, commonly
referred to as the cloud computing stack. These include Infrastructure as a Service (IaaS),
Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS delivers virtualized
computing resources over the internet, allowing organizations to provision and manage
servers, storage, and networking infrastructure on-demand, without the need for physical
hardware. PaaS provides a platform for developing, deploying, and managing
applications, abstracting away the underlying infrastructure and enabling developers to
focus on building and scaling software solutions. SaaS delivers software applications
over the internet on a subscription basis, eliminating the need for organizations to install,
maintain, and update software locally.
The benefits of cloud computing are manifold, offering organizations unparalleled agility,
scalability, and cost-efficiency. By leveraging the elasticity of cloud infrastructure,
organizations can rapidly scale computing resources up or down in response to changing
demand, ensuring optimal performance and resource utilization. Additionally, cloud
computing eliminates the need for large upfront investments in hardware and
infrastructure, replacing capital expenditures with predictable operational expenses based
on usage. Moreover, cloud computing fosters innovation and collaboration by providing
ubiquitous access to computing resources and enabling organizations to experiment,
iterate, and deploy new ideas at scale.

However, despite its many advantages, cloud computing is not without its challenges.
Chief among these is the issue of security and data privacy. Entrusting sensitive data and
critical workloads to third-party cloud providers introduces inherent risks, including data
breaches, compliance violations, and unauthorized access. Furthermore, the complexity
of managing cloud environments across multiple vendors and platforms can present
governance, risk, and compliance challenges for organizations, necessitating robust
security measures, encryption protocols, and access controls to safeguard sensitive
information and mitigate security threats.
Another key consideration in cloud computing is vendor lock-in, whereby organizations
become dependent on a single cloud provider for their infrastructure and services,
limiting flexibility and interoperability. To mitigate the risks associated with vendor lock-
in, organizations must adopt a multi-cloud or hybrid cloud strategy, leveraging multiple
cloud providers and platforms to diversify risk, increase resilience, and avoid reliance on
any single vendor. Additionally, organizations must carefully evaluate cloud service
agreements, service-level agreements (SLAs), and exit strategies to ensure they maintain
control over their data and applications in the event of provider changes or service
disruptions.
In conclusion, cloud computing represents a paradigm shift in the way organizations
leverage technology to drive innovation, agility, and growth. By providing on-demand
access to scalable computing resources and services over the internet, cloud computing
enables organizations to accelerate digital transformation, optimize operational
efficiency, and unlock new opportunities for collaboration and innovation. However, to
realize the full potential of cloud computing, organizations must address key challenges
related to security, compliance, and vendor lock-in, while embracing best practices and
strategies for cloud adoption and management. Ultimately, cloud computing promises to
reshape the future of computing, empowering organizations to thrive in an increasingly
interconnected and digital world.

Fundamentals of Software Testing
Software testing is a critical component of the software development lifecycle (SDLC),
encompassing the process of evaluating a software application or system to identify
defects, errors, and discrepancies between expected and actual behavior. By
systematically verifying and validating software against predefined requirements and
specifications, testing helps ensure the quality, reliability, and functionality of software
products, ultimately enhancing user satisfaction and reducing the risk of software failures
and defects in production environments.
1. Principles of Software Testing
The principles of software testing serve as guiding tenets for designing and executing
effective testing strategies. These principles include:
• Testing Shows the Presence of Defects: The primary objective of testing is to
identify defects in software. However, the absence of detected defects does not
necessarily imply the absence of defects altogether; it simply indicates that
defects have not been found yet.
• Exhaustive Testing is Impossible: Given the infinite number of possible inputs,
paths, and scenarios in a software application, it is impossible to test every
possible combination exhaustively. Instead, testing efforts should be focused on
high-risk areas and critical functionalities.
• Early Testing: Testing should be conducted early and continuously throughout
the software development lifecycle to detect defects as early as possible when
they are less costly to fix. Early testing helps prevent defects from propagating to
subsequent stages of development.
• Defect Clustering: A small number of modules or functionalities typically
contain the majority of defects. By focusing testing efforts on these high-risk
areas, testers can maximize defect detection efficiency.
• Pesticide Paradox: Test cases that initially detect defects may become less
effective over time as the software evolves. To combat this, test cases should be
regularly reviewed, updated, and supplemented with new test cases to uncover
previously undetected defects.
• Testing is Context-Dependent: The effectiveness and appropriateness of testing
techniques, tools, and methodologies depend on the context of the software being
tested, including its requirements, technology stack, domain, and constraints.
2. Testing Techniques and Strategies
Software testing employs a variety of techniques and strategies to systematically uncover
defects and validate software functionality. Some common testing techniques include:
• Black Box Testing: Black box testing focuses on testing the external behavior of
a software application without knowledge of its internal code structure. Testers
7. 7
design test cases based on input-output specifications, functional requirements,
and system interfaces to validate the correctness and completeness of software
functions.
• White Box Testing: White box testing, also known as structural testing or glass
box testing, examines the internal logic, structure, and code implementation of a
software application. Testers design test cases based on code paths, control
structures, and code coverage criteria to uncover logical errors, programming
bugs, and optimization opportunities.
• Gray Box Testing: Gray box testing combines elements of black box testing and
white box testing, allowing testers to leverage both external and internal
knowledge of the software under test. Gray box testing is particularly useful for
integration testing, where testers have partial access to internal code and system
architecture.
• Regression Testing: Regression testing verifies that modifications to a software
application or system have not introduced new defects or regression bugs while
maintaining existing functionality. Testers execute a suite of previously validated
test cases to ensure that changes do not adversely impact software quality or
stability.
• Exploratory Testing: Exploratory testing involves simultaneous learning, test
design, and test execution, allowing testers to explore software functionality,
uncover defects, and gain insights into system behavior in real-time. Exploratory
testing is often used in agile and iterative development environments to
complement scripted testing approaches.
• Acceptance Testing: Acceptance testing validates whether a software application
meets the specified business requirements and user expectations. It is typically
performed by end-users or stakeholders to assess software readiness for
production deployment and acceptance.
3. Importance of Testing in Software Development Lifecycle
Software testing plays a pivotal role in the software development lifecycle, contributing
to the overall quality, reliability, and success of software products. Throughout each
phase of the SDLC, testing activities help identify and rectify defects, ensure compliance
with requirements, and mitigate project risks. The key stages of the software development
lifecycle where testing is integral include:
• Requirements Analysis and Planning: During the requirements analysis phase,
testing activities involve eliciting, clarifying, and validating user requirements to
ensure they are clear, complete, and testable. Test planning involves defining
testing objectives, scope, resources, and timelines, as well as identifying test
scenarios, test cases, and testing environments.
• Design and Development: In the design and development phase, testing
activities focus on validating architectural designs, system specifications, and
software components against functional and non-functional requirements.
Developers write unit tests to verify the correctness of individual code units,
8. 8
while testers conduct integration testing to validate the interaction and
interoperability of integrated components.
• Testing and Quality Assurance: The testing and quality assurance phase
encompasses a variety of testing activities, including system testing, integration
testing, performance testing, security testing, and user acceptance testing (UAT).
Testers execute test cases, analyze test results, report defects, and verify bug fixes
to ensure software meets quality standards and user expectations.
• Deployment and Maintenance: Even after software deployment, testing remains
an ongoing process to support maintenance, updates, and enhancements. Testers
perform regression testing to validate changes, monitor system performance, and
gather feedback from end-users to identify opportunities for continuous
improvement.
In summary, software testing is a fundamental aspect of the software development
lifecycle, providing critical feedback and validation throughout the development process.
