A software product is defined by the quality of its features, security, availability, its extensibility in the future along with many other factors. Building the right product using modern technologies is one thing, but choosing the right components while keeping in mind the objectives of key stakeholders when deploying a solution to the cloud is another thing and can be a daunting task. Several factors drive the design decisions while building the right architecture for your product in the cloud. Different teams, from banking lines of business, compliance to IT delivery and operations, have varying needs when it comes to how they leverage and manage the technology day to day. Cloud providers offer a wealth of managed services and hence the balance between choosing these services, their benefits, and the associated costs should be taken into consideration by the key stakeholders when making such decisions. Primarily, cloud components are categorized into hardware, virtualization, storage, and network, and should be chosen carefully when designing solutions. Some major factors taken into consideration are:
This Google Cloud managed service is a key part of this architecture, restricting access to components behind the gateway with private IPs. Cloud NAT provides network address translation for subnets in the VPC region with a single gateway. In simple words, it lets the internal resources and its components create outbound internet connections when needed for upgrades and other similar necessities. It was carefully chosen during the design phase as a component of this architecture to ensure security to the internal resources of the system.
The services of NCR Authentic Cards are exposed to the customers through Cloud Load Balancing which is a fully distributed, software-defined, and highly scalable managed service provided by Google Cloud. Cloud Load Balancing helped in deploying the entire product behind one anycast external IP which is called by the customers to avail the services. NCR Authentic Cards can be deployed in multiple regions for failover, availability, and geographical needs behind this single IP. Also, the product and its resources can be auto scaled as required without impacting the customers. Cloud Load Balancing also supports SSL offloading, which means that the incoming SSL traffic from the customers is terminated at the load balancer and not sent as-is to the internal servers, providing an additional layer of security.
The architecture of NCR Authentic Cards uses Apigee API management as the gateway to handle external traffic. Apigee routes traffic through the load balancer as well but independently authorizes each transaction at its layer using OAuth 2.0 API proxy. Apigee provides full API lifecycle management capabilities that support the always evolving and expanding card services integration ecosystem while offering the option to monetize API products. This allows for the solution to constantly offer new endpoints and a wider set of connectors for internal and external systems. The Authentic Card APIs are mapped to API proxies in Apigee which allows policies to be defined at the proxy level for security and other requirements. The default policy applied to the API proxies is VerifyAccessToken, helping to ensure token authentication for all the APIs. The Apigee architecture for Authentic Cards is depicted in the diagram below.
The Opus codec scales from 6 kbit/s narrowband mono speech to 510 kbit/s fullband stereo music. It can seamlessly switch between all of its various operating modes, giving it a great deal of flexibility to adapt to varying content and network conditions without renegotiating the current session.
Unlike using an online builder that only uses templates, you are fully in control. This means that you are NOT building a templated site! You can design and build a completely custom website and not feel confined to predefined content blocks. All the structure and design is completely up to you.
The abbreviation is used in an endnote or footnote to refer the reader to a cited work, standing in for repetition of the full title of the work. Op. cit. thus refers the reader to the bibliography, where the full citation of the work can be found, or to a full citation given in a previous footnote. Op. cit. should never, therefore, be used on its own, which would be meaningless, but most often with the author's surname, or another brief clue as to which work is referred to. For example, given a work called The World of Salamanders (1999) by Jane Q. Smith, the style would typically be "Smith op. cit.", usually followed by a page number, to refer the reader to a previous full citation of this work (or with further clarification such as "Smith 1999, op. cit." or "Smith, World of Salamanders, op. cit.", if two sources by that author are cited). Given names or initials are not needed unless the work cites two authors with the same surname, as the whole purpose of using op. cit. is the economy of text. For works without an individually named author, the title can be used, e.g. "CIA World Fact Book, op. cit." As usual with foreign words and phrases, op. cit. is typically given in italics. The variant Loc. cit., an abbreviation of the Latin phrase loco citato meaning "in the place cited", has been used for the same purpose but also indicating the same page not simply the same work; it is now rarely used or recognized.
OPUS is the new generation of spectral sensors for online measurement of nitrogen and carbon compounds. Through the analysis of a full spectrum, OPUS is able to deliver reliable readings for NO3-N, NO2-N, organic ingredients (CODeq, BODeq, DOCeq, TOCeq), and a number of other parameters.
One unique feature of Opus is that it works for both sampling human voices and music. The human voice uses a relatively limited range of frequencies most of the time, and therefore can be compressed more easily into what is referred to as narrowband. Narrowband voice has a subtle, but noticeable distortion when you hear it. Wideband audio that captures the entire human speech range is what most speech oriented codecs strive for. Music, on the other hand, encompases the full spectral range of what our ears can hear. Coding these extra features takes more bits and is typically referred to as fullband.
As mentioned, Opus is a versatile codec with flexibility on how much bandwidth is consumed. In most cases where the users are on the internet and optimum performance is a possibility, implementers should allow the default full sampling at 48kHz and allow the codec to auto-tune to the audio input and network conditions.
To search for an organization with more than 1 NPI users will need to use the Search by NPI feature. This feature will return a single NPI when only one NPI exists for the organization or provider or will return the grouping of NPIs for the organization with multiple NPIs that the NPI belongs to. The user can then select the organization and see all the NPIs associated to it. This search requires the entry of the full (10 digit) NPI number. 2b1af7f3a8
