One of the questions I get asked a lot by my customers is “How can I get the most out of my Office 365 subscription?” My answer is always “Start using Microsoft® Teams!”

In the financial services sector, Salesforce® stands head and shoulders above the other customer relationship management (CRM) and cloud computing platforms out there. That’s because Salesforce designed its Financial Services Cloud with financial services in mind, enabling you to connect with your clients more personally than ever before.

This blog describes the SAP® Plant Connectivity (PCo) services and management tools that enable you to integrate with SAP Manufacturing Integration and Intelligence (MII) to create the following elements:

• Connectors
• Communication paths between control systems
• Control devices
• Files
• Historians
• Transmission Control Protocol (TCP) sockets

It is one thing to have access to Salesforce® within your organization; it is another be confident that you are using the platform to its full capacity.

What happens if you discover that your organization’s Salesforce usage is below the curve? Don’t lose hope. It might take time to fully capitalize on the many ways that Salesforce can empower your team. Here are four strategies to help you develop a workable plan of action.

Interaction Studio launched in 2018 as an innovative Marketing Cloud feature that enables your company to engage with customers at every stage along the path from lead to loyalty. Interaction Studio uses cookies to track customer data and then matches that data with customer-provided information—like email addresses and phone numbers.

Salesforce®Community Cloud offers a centralized platform for loyal customers, happy employees, and engaged partners. Community Cloud is a Salesforce application that allows your organization to create online forums (communities) where members can communicate with each other and with the organization.

Do you ever feel that the analytics you get from Salesforce® Classic Reports and Dashboards isn’t providing enough insight for your organization’s goals?

If you feel like you’re not leveraging your data as effectively as you could, you have likely matured past what Classic Reports can do. The solution is to turn to Salesforce’s stronger reporting platform, Einstein Analytics.

Modern browsers have APIs called querySelector and querySelectorAll. They find one or more elements matching a CSS selector. I'm assuming basic familiarity with CSS selectors: how you select elements, classes and ids. If you haven't used them, the Mozilla Developer Network has an excellent introduction.

Running a successful developer workshop (aka tutorial) is really difficult. I've attended enough workshops that have gone poorly to know that for a fact. Participating in such a workshop can be very frustrating and a huge turn off for whatever technology is being presented. That translates directly into losing developer mindshare. I think we, as an industry, can do a better job of running developer workshops.

When we, at Rackspace were working on a data visualization dashboard which uses AngularJS framework, we needed to abort requests. Fortunately, AngularJS has amazing built in services of which $http and $resource helped us make these XHR(Ajax) requests much simpler. There are many resources to figure out which might be better for your use case. I’m going to describe how I implemented aborts in $resource and $http in an unified way which increased the performance and showed correct data.

If you're a big PostgreSQL fan like I am, you may have heard of a tool called WAL-E. Originally developed by Heroku, WAL-E is a tool for efficiently sending PostgreSQL's WAL (Write Ahead Log) to the cloud. In addition to Heroku, WAL-E is now used by many companies with large PostgreSQL deployments, including Instagram.

Let's unpack what that means. If you've ever set up replication with PostgreSQL you're probably familiar with the WAL. Essentially there are two parts to replication and backup in PostgreSQL, the "base backup" and the WAL. Base backups are a copy of your database files that can be taken while the database is running. You might create base backups every night, for example. The WAL is where PostgreSQL writes each and every transaction, as they happen. When you run normal replication, the leader will send its log file to the followers as it writes it.

Instead of just using a simple socket to communicate, WAL-E sends these base backups and WAL files across the internet with the help of a cloud object store, like Cloudfiles (or any OpenStack Swift deployment). This gives you the advantage that, in addition to just being replication, you have a durable backup of your database for disaster recovery. Further, you have effectively infinite read scalability from the archives, you can keep adding more followers without putting more stress on the leader.

With the help of WAL-E's primary author, Daniel Farina, we recently added support for OpenStack Swift to it. It's not yet in a final release, but if you're interested in checking it out, read on!

One of the more pressing needs in the world of open source software is the need for decent documentation. That covers a lot of territory; from well-commented code (yeah… right) to API guides to the rare – some say mythical – user guide.

It's that last one, the user guide, that is often either not created or – perhaps worse – created as an afterthought by a developer whose writing skills are better aligned with Javascript than [Strunk][1]. When I joined the Developer Relations Group at Rackspace in July (be sure to check out the [Rackspace Developer Center][2] if you haven't already), I immediately decided to create a user guide for the [OpenStack SDK for Microsoft .NET][3]. While creating that document, I realized that many developers don't have a passion for writing documentation. Fair enough – I've never watched Game of Thrones. So, as a former sportswriter and an active coder (C# is my poison, mobile apps my passion), I have come up with a list of guidelines to help you craft a Pulitzer-worthy user guide. These suggestions (11 of them, yup, my list goes to 11!) were not developed through any sort of scientific process; rather, they are the result of more years of experience than I care to admit.

The hardest part about using new technology is knowing where to begin. Spending hours sifting through blog posts and documentation to set up a server environment is often enough to extinguish the excitement about a new framework or application. By the same token, it is frustrating to deploy hosting architecture when you are excited to see how your latest code will perform. And no one likes having to do the same things over and over to create consistent testing, staging and production environments.

Deploying your application to the cloud requires expertise in both system administration and development; often, people have expertise in some areas while having gaps in others. The Rackspace Deployments service was created so we could collect this information and expertise in machine and human readable format and use it to automatically and consistently deploy hosting configurations, frameworks and applications and alleviate some of this stress.

I am part of a team (along with Bruce Stringer and Jason Swindle) working on an internal application called Graffiti, which provides an easy way for front-line Rackers to record interactions with customers and provide valuable data with each interaction. It also creates a much simpler way for leads to be passed from the front line to the IB sales team here in SMB cloud.

We knew from the start that we wanted this to be an agile cloud application that utilizes all the things a cloud should be. We had some limitations which meant we had to home grow a few solutions. Since this is an internal application, we could not rely on third-party solutions for off loading workloads. We also had to be careful with our security practices, of course. We ended up going with a configuration that utilizes our internal nova solution for hosting in Cloud Servers. The downside to this is that we have no automated backups, no load balancers and no Cloud Files - much to my dismay.

Agile. Scrum. Extreme programming. RAD. Lean. These terms all represent a departure from the traditional Waterfall development process in favor of a more rapid, iterative approach to application development. For companies with large-scale web applications, there are significant benefits to the agile methodology, but it also presents significant challenges.

When every minute of downtime represents significant lost revenue and increased support costs, it stands to reason that application support should be just as agile as application development. Among other things, this means tearing down l ong-standing walls between teams, and getting all business units working together toward common goals.
