Comparison of Several PaaS Cloud Computing Platformsijsrd.com
Today, the question is less about whether or not to use Platform as a Services (PaaS), but rather which providers to use. PaaS is a computing platform that abstracts the infrastructure, OS, and middleware to drive developer productivity. PaaS offerings are "polyglot" and "polyhost". Selection of Platform as a Service provider is an important process because an ideal vendor will be able to continue to partner with company as company grows. There are many components to be consider while selecting PaaS vendor like Scalability, Availability, Manageability, Performance, Security, Accessibility, Billing At a high-level a PaaS helps organizations, specifically by providing a fast and scalable way to host applications in the cloud.
Comprehensive Information on Platform as a ServiceHTS Hosting
This document provides an overview of Platform as a Service (PaaS) including definitions, characteristics, advantages, when to use PaaS, and challenges. PaaS provides developers a platform to build, run, and manage applications without having to maintain the infrastructure. It can offer scalability, ease of development and deployment, high availability, and reduced costs. However, challenges may include integration issues, customizing legacy systems, loss of operational control, vendor lock-in, runtime issues, and data security risks.
Cloud computing is a style of computing in which scalable and elastic IT capabilities are delivered as a service using internet technologies. Key aspects include resources that are scalable and metered by use, and may be single-tenant or multi-tenant and hosted remotely or on-premises. Self-service interfaces like web UIs and APIs are exposed directly to customers. Cloud services can provide software, platforms, infrastructure, integration capabilities, and everything as a service (XaaS). The major cloud providers offer various capabilities and are competing on features, price, and services beyond basic compute and storage.
This document summarizes key points from a lecture on virtualization and cloud computing:
1. Nearly everyone uses cloud services directly or indirectly through applications like GitHub. Companies are moving more business operations to cloud services and platforms.
2. Cloud services provide on-demand, scalable resources that users pay for based on usage. Key cloud service models are SaaS, PaaS, and IaaS.
3. SaaS delivers software through subscriptions. PaaS provides development tools and platforms in the cloud. IaaS offers virtual infrastructure like servers, storage, and networks on demand.

This document discusses building and using a DevOps-driven migration pipeline for workload portability between cloud platforms. It outlines several key challenges with application migration including a lack of visibility into application dependencies and architectures. The document then presents HPE Pointnext's workload portability services which use automation and DevOps practices to discover, map, migrate, and optimize workloads for multiple cloud targets. It describes the engagement process and use of tools to rationalize workloads and implement a DevOps style migration pipeline to deploy applications across platforms in a standardized manner.
This document discusses building cloud applications faster using Platform as a Service (PaaS). It defines characteristics of cloud-optimized applications like multi-tenancy and elastic resource consumption. RESTful APIs are identified as the language of the cloud for loosely coupling services. Benefits of using PaaS over Infrastructure as a Service (IaaS) are lower development and deployment costs as well as application portability. The document provides examples of PaaS and SaaS services and recommends focusing on unique functionality rather than rebuilding existing services. It outlines considerations for evaluating PaaS options like supported services, deployment preferences, and application strategy fit.
The document summarizes key topics in cloud computing including definitions of cloud types (private, public, hybrid, community), characteristics of cloud services (on-demand self-service, broad network access, etc.), cloud service models (SaaS, PaaS, IaaS), benefits and risks of cloud adoption, security considerations, and predictions for cloud computing in 2012.
The document discusses cloud computing from the perspectives of application developers, quality assurance teams, and enterprises. It provides rationales for why cloud computing can reduce capital expenditures and operational expenditures compared to maintaining their own on-premise hardware and software. The document also summarizes the NIST definition of cloud computing and describes its essential characteristics, service models, and deployment models.
Webinar presentation: November 15, 2016
The topics of interoperability and portability are significant considerations in relation to the use of cloud services, but there is confusion and misunderstanding of exactly what this entails.
Interoperability and Portability for Cloud Computing: A Guide provides a clear definition of interoperability and portability and how these relate to various aspects of cloud computing and to cloud services.
This webinar will describe interoperability and portability in terms of a set of common cloud computing scenarios. This approach assists in demonstrating that both interoperability and portability have multiple aspects and relate to a number of different components in the architecture of cloud computing, each of which needs to be considered in its own right. The aim is to give both cloud service customers and cloud service providers guidance in the provision and selection of cloud services indicating how interoperability and portability affect the cost, security and risk involved.

The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
The cost of acquiring information by natural selectionCarl Bergstrom
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

Or: Beyond linear.
Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.

Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

11. How can we tackle portability threats?
Standardization
– Portability of applications
• Single unit of delivery including all dependencies
• e.g. Docker containers, TOSCA
– Portability of application dependencies
• e.g. standardized buildpacks
Lack of acceptance by industry leaders prevents adoption
11
12. How can we tackle portability threats?
Rely on native support and open technologies
+ No intermediaries, instant applicability!
+ There are common setups that are often used by
developers
+ Vendors want to attract many customers, so the
environmental setups should intersect
