The Government’s “Cloud First” policy of 2011 set an accelerated course of government technology migration to cloud resources. The benefits of cloud services and infrastructure are appealing for use in simulation and training for many reasons, including the ability to provide point-of-need (PoN) simulation, freedom from hardware maintenance and upgrades, reduction of capital expenditure and hardware footprint, and practically limitless resources that allow ease of scalability. Evaluation of the fitness of visual system service for migration to the cloud as per the cloud-first guidance of readiness and value is highly dependent on the intended use case and architecture of a cloud-based simulator.

While attractive in concept, serious limitations in training quality and effectiveness can exist depending on the implementation strategy of a cloud-based visual system. This paper explores the technical challenges and functional ramifications of distributing visual system components across the cloud compared to on-premises resources.

Topics include: Latency, performance, distributed visual system architectures, latency tolerance of basic visual system components, and edge device computing.

A wide spectrum of use cases exist within the simulation and training realm, and cloud-based visual systems must provide a flexible and adaptable hybrid cloud architecture to achieve required goals across very diverse training needs and physical infrastructure.

Storage at the Edge Competes on Cost and Complexity

In part one of this blog series, we suggested there are scenarios where storage in close proximity to compute systems offered advantages over cloud options.

It certainly is cloudy. That’s the takeaway from RightScale’s 2018 Annual State of the Cloud Report.
• “96% of Respondents Use Cloud”
• “81% of enterprises have a multi-cloud strategy”
• “Organizations Leverage Almost 5 Clouds”

High-performance storage close to the compute source is not only relevant but also much less complex and costly than it once was, thanks in large part to the emergence of software-defined storage. Where cloud technologies rely on virtualized platforms, software-defined advancements allow optimized, scalable storage solutions that offer accessibility, control, data ownership, security, and more.

So what is software-defined storage? In the simplest terms, software-defined storage is a layer of abstraction that hides the complexity of the underlying compute, storage, and in some cases networking technologies. It’s a viable option, as organizations continue to express concerns over data security, leaks, capabilities, and capacity of cloud-based options.

The trend that follows is “software-defined everything,” including software-defined networking or software-defined virtual function. Hyperconvergence is next, which is a strategy that brings together infrastructure components such as compute, storage, virtualization, networking, and bandwidth onto a single platform and defines it in a software context.

Engineering a Future: Tips for Creating a Career Path in Technology

Engineering is everywhere in our society – it’s a versatile career choice that makes a difference in the world. Students who have committed to this path might be wondering how to get started in their careers, or even how to focus their field of study within a vast array of options. Newly employed engineers may question how to design a path forward, even as they focus on their day-to-day job roles. These issues are relevant for anyone designing a future for themselves in the field of engineering. With some shared insight and common sense tips, you can better refine your interests and be proactive in developing a fruitful career path.

FIND YOUR CALLING

Engineering school.jpgTypically, if you attend a four-year university with an engineering program recognized by ABET (Accreditation Board for Engineering and Technology), your early years include classes such as physics and chemistry. Try to weave in a variety of engineering introduction courses as well. While your first instinct as a student might be to avoid classes of indirect interest, it is wise to invest time in getting a taste of the real differences between fields of engineering study.

Institutions such as MSOE (Milwaukee School of Engineering) do a great job of developing curriculum that allows student to experience entry-level instruction in a range of engineering disciplines without slowing down progress toward a chosen degree. These opportunities can vary greatly from college to college, so take the initiative to go over course selection before locking into a specific university and be sure to capitalize on academic advisement at every step.

CAPITALIZE ON OPPORTUNITIES FOR EXPERIENCE

Internships and co-ops are critical in distinguishing yourself among the crowd. These real-world experiences can also help further refine your direction in terms of choosing a profession. For example, maybe math has always called to you, but an ‘on-the-job’ experience reveals a greater interest in programming. Taking on outside activities of your own can make a difference as well, for example a project like building a remote-controlled car from the ground up. Develop the design, create the circuit board – these types of activities show you are an engineer at your core. Employers love to see that you love to engineer.

As a student, cover the basics. Carry your resume. When business leaders are on campus, stop by the booth or classroom. They are there to connect, so ask a few questions and take a business card. When more structured settings are offered, participate. For example, several times during the school year MSOE features a local technology business at a hosted dinner event. Embrace the presentation and the opportunity to connect in a mixer setting. Go to the career fairs, even if you’re a freshman. Students can never have too much experience interfacing with future employers. Join the student chapters of professional organizations such as IEEE (Institute of Electrical and Electronics Engineers) and ACM (Association for Computing Machinery). Besides looking good on a resume, these groups connect students with people and information.

MIMICKING REAL WORLD EXPERIENCE IN SCHOOL

Gaining technology experience is another top student goal. MSOE’s software development lab provides an example of how real-world experience can be gained in a classroom setting. Juniors have access to this year-long program – students are teamed up in small groups and matched with local businesses who volunteer to participate at a high level. Each team owns responsibility for development of a product, while the business contact becomes a leader and mentor throughout the process.

Experience here goes beyond development of the actual software, and students get an excellent introduction for how to demo software to a manager. Feedback is typically more critical and in-depth because it comes directly from a business leader accustomed to caring about a product’s level of perfection. Learning how to deliver and present a finished product is an invaluable experience for students preparing to step into the professional world.
