This document discusses availability options for SharePoint server farms. It begins by covering common causes of downtime in SharePoint like hardware failures, network issues, and human error. It then describes the limited high availability (HA) and disaster recovery (DR) capabilities that SharePoint has built-in, such as server redundancy and a secondary farm. Third-party options are presented as providing more robust protection than what is included with SharePoint, like rapid backup/recovery, replication, virtualization, and clustering. Neverfail is highlighted as a solution that can monitor entire SharePoint farms, enable automated failover across sites for HA and DR, and protect all SharePoint components through a single management interface. Determining the right availability solution involves

As data centers are modernized to provide Infrastructure as as Service (IaaS) on premise and leverage IaaS in partner and public hosted clouds, customers will want guidance on how to implement resilient solutions in either environment and hybrid implementations. With PaaS, the focus of FailSafe has largely been on the application developer, but experience during the IaaS preview shows that many of the people we talk to about are IT Pros who are more interested in setting up the infrastructure that applications can be developed on. This session will focus on patterns and implementation guidance for delivering resilient IaaS implementations for that audience.

Better Payroll Days Ahead with Automated, Cloud-Based Time and Attendancenettime solutions
Processing payroll may not be a day at the beach, but it doesn’t have to be a chore. According to the IRS, 33% of employers make costly payroll errors each year that result in billions of dollars in penalties. Why does this happen? We all know that payroll isn’t just about adding up the hours an employee works over a period of time, multiplying those hours by a rate, and then cutting the employee a check. There is a seemingly endless list of variables to factor in, such as local, state and federal labor law compliance (such as the ACA); PTO accruals; job costing; expense tracking for items such as tips or uniform deductions; and the list goes on and on. Multiply all of that by different pay policies for different groups of employees, and take into account union versus non-union workers, and the payroll process becomes even more complicated. In this free webinar, nettime solutions will show you how using automated, cloud-based time and attendance with web service integrations will convert your payroll processing chores into big wins for your company by eliminating errors, improving productivity, and maintaining data integrity so that payday is a great day for everyone involved.

Architecting and Tuning IIB/eXtreme Scale for Maximum Performance and Reliabi...Prolifics
Abstract: Recent projects have stressed the "need for speed" while handling large amounts of data, with near zero downtime. An analysis of multiple environments has identified optimizations and architectures that improve both performance and reliability. The session covers data gathering and analysis, discussing everything from the network (multiple NICs, nearby catalogs, high speed Ethernet), to the latest features of extreme scale. Performance analysis helps pinpoint where time is spent (bottlenecks) and we discuss optimization techniques (MQ tuning, IIB performance best practices) as well as helpful IBM support pacs. Log Analysis pinpoints system stress points (e.g. CPU starvation) and steps on the path to near zero downtime.
Systems on the edge - your stepping stones into Oracle Public PaaS Cloud - AM...Lucas Jellema
Adoption of the cloud will not start with the core enterprise applications. There are several ways to start the adoption. One is to move in from training environments through development and test to production. Another takes the importance of applications into consideration, starting with secondary, supporting systems. The approach discussed in this session is to start with edge systems that are already in the DMZ, on the fringes of an enterprises, where they engage in interaction with the outside world.
Systems on the edge of an enterprise have special challenges regarding availability, scalability, security and external interactions with systems or people. This applies for example to external portals, B2B interactions, workflows that involve external actors, mobile APIs and integrations with SaaS instances. These systems are obvious candidates to move to a public cloud - and handle these special requirements on the PaaS platform. This session discusses and demonstrates a number of Oracle PaaS Cloud Services, their mutual interaction and how they can be leveraged to move these systems over the edge and into the cloud: Java Cloud Service, Integration Cloud Service, Process Cloud Service, IoT CS, Mobile Cloud Service, SOA Suite Cloud Service and Message Cloud Service. We will go over a number of scenarios for moving edge systems from on premises to the public cloud. Essential in this discussion is of course the integration from the edge system in the Oracle Public Cloud to the on premises backend systems.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Choosing the Right Solution for SharePoint
– Consider the cost of downtime
– How critical is your SharePoint infrastructure to you business?
– Consider the possible vulnerabilities
– What scenarios do you need to protects yourself against?
– Consider the availability options
– Which solution covers the vulnerabilities you need protection from?
– Neverfail provides the most robust affordable solution for
SharePoint and any other Windows-based application
26. 26
Key Technology Differentiators
– Protects End-to-End Business Services
– Neverfail aggregates & protects any set of multi-tier components,
including applications, servers, services, and it maps all their
interdependencies
– Complete Protection Against the Widest Range of Failures
– Leverages Application Awareness, Intelligence and Automation
– Eliminates both planned and unplanned downtime
– WAN Acceleration & Deduplication
– Essential feature set to enable DR deployments
– Heterogeneous Protection
– Physical and Virtual Environments (P2P, P2V, V2P, V2V)
– Any Combination of Physical Server and Storage Hardware
There are many things that can impact system availability, from single-component hardware failures to site-wide environmental issues. Even simple things like routine maintenance can have an unexpected impact on the systems being maintained. There’s a lot of truth to the saying that the biggest cause of unplanned downtime is actually planned downtime. It’s easy to understand that any single system is vulnerable on many different levels. With critical-point systems like a SQL Server database, an outage on one system has an instant impact on the availability of one or more end-user applications. It really isn’t a question of will there be downtime, but rather when will there be downtime. Planning for this unexpected downtime is the first big step in avoiding the impact it could have on your company.Environmental issuesPower outages, cooling failures, natural disastersHardware issuesComponent failures in a single host, storage-related failuresConnectivity issuesNetwork component failures, building connectivity, ISP outagesPlanned maintenanceHardware upgrade, routine OS patch installationNetwork latency issuesDistributed farms require low-latency network connectionsDatabase availabilitySQL Server requires protection from downtime as wellHuman errorInconsistent installations, undocumented changes, process errors
SharePoint’s built-in HA based on server redundancyAlmost every layer of the application stack can have a second instance installedSome components are unique and exist only onceSharePoint availability also depends on the databaseSome (different) form of HA is required at the SQL layerDid you catch our “30 Minutes to SQL Server Availability” webcast?Limited to local subnets & low-latency linksSometimes called a stretch farmNot suitable for moving SharePoint to a remote site
Complete second SharePoint farm in another locationReally an entirely separate SharePoint installationRequires diligent maintenance of applications and serversEvery SharePoint package deployed in prod also needs to be deployed in DRRequires some form of database replication for SQL ServerDatabase layer is “shared” by both farmsOnly one farm can actively write to the database
No single point of control - Multiple technologies, Manual coordination, Scripted task dependencies= Complexity, Cost & RiskNo Application Awareness= Risk of DowntimeNo Application Server failover= Risk of DowntimeIndex Server Single Point of Failure= Risk of Loss of Search ServiceLow latency & high bandwidth req., Third server req. for automation = Cost & Distance Limitations
3rd party options are solutions are designed to add value over what available “out of the box” from an application-based solution. Take maybe stretch-farms or SQL database mirroring for example. If say for example that you have stringent RTO or RPO requirements, the built-in options may not go far enough to meet you needs. You may also be looking to protect yourself against a broader range of failures. Many solutions provide protection from a hardware failure, but troubles within the operating system or the application itself still result in availability issues. Some solutions architectures even allow a company to run an application during regular planned maintenance events.Using 3rd-party solutions can simplify HA infrastructure and DR planning as one solution may be employed across a wide range of server technologies, often from a single location. Companies can recognize even lower cost of ownership through reduced training & infrastructure costs when using a single solution can be deployed throughout the environment.
When we talk about “third party solutions”, that can cover a lot of different technology approaches. While some are better than others, each comes with their own set of strengths and weaknesses. Almost every kind of solution falls into one or more of the following categories….
Application-level backupsGranular site-level, document-level recoveryDisk-based backupFast, frequent block-level differential backupVirtual recovery capabilitiesRecover into a VM created from a disk backupAccelerated data recoveryReduces recovery window following a failureBackup solutions have been around for a long time, and honestly they’re light-years better than they were when I first joined the industry. There are different kinds of backup, such as those that work with a specific application. These solutions enable very granular recovery options and often the ability to perform versioning control and other data management operations. System-level backups are much better now too, not only utilizing more dependable disk-based arrays before going to tape, but also by backing up more raw changes instead of entire documents or databases.Some backup solutions now offer the ability to recover into a virtual machine file created from a system backup. This is nice for preventing significant downtime during working hours, but keep in mind that at some point you still need to recover the original server and this stopping the VM before taking one last backup and starting the recovery process. While today’s solutions have ways of making the data recovery process seem faster, the fact that you’re doing a recovery at all is because there was a failure in the first place.

Traditionally, servers of like functionality are grouped together for availability/protectionYou might have a different solution in place for each different type of technology used in your application.This kind of approach leads to complexity of the overall solution, reduces the “usability” of the solution, and ultimately affects the cost of ownership and time to recovery in the event of a disaster.
Neverfail takes a Business-Centric approach and manages and protects the completeBusiness application.Neverfail’s unique Business-centric approach manages and protects the complete Sharepoint Farm, including:
Our value proposition is about keeping users permanently connected to their applications. Allowing access to what they need when they need it.Our Total Cost Of Ownership equation = No loss of productivity + meeting or exceeding SLA’s + preventing reputational damage. Service interruptions cause a loss of productivity; the cost of one minute of downtime multiplied by the number of business users in an organization can be surprisingly costly. As can the financial penalties associated with not meeting Service Level Agreements. And service interruptions can also lead to a loss of confidence in the IT function and damage the credibility of the CIO with the business. Reputational damage is hard to put a price on.Our technology will enable reputations to be protected and SLA’s to be maintained or even exceeded by maintaining service continuity through interruptions and application maintenance windows that normally require downtimeIn summary Neverfail enables Enterprise Data Centre levels of high availability and disaster recovery based on cost effective “Wintel” commodity technology.
