Amazon EC2 regions and Windows Azure affinity groups - Security Considerations -

-

i read regions , affinity groups in amazon ec2 / windows azure. seems used first , foremost assure performance.

what concerned security. can these services "switch" region , transfer of data in cloud region if have performance bottle neck? couldn't find information far.

for employer it's important data never crosses regions since our clients demand data stays on european data centers.

in azure, affinity groups abstraction concept tells fabric controller best ensure groups of related services deployed ensure optimization inter-app communication. groups ensure services, storage, etc placed in close proximity whenever possible.

affinity groups bound regions, don't need worry ag switching countries on own, bound region.

in azure, explicit geo-location concept of region. if specify region binding datacenter (or virtual concept of dc) in particular geographical region. @ time there no ability move/migrate services among regions on own.

the fabric controller replicate across physical datacenters fault tolerance, action bound country-specific nature of region definition. datacenter 1 in north central replicated datacenter 2 in south central us, never european region. "anywhere" regions let fc determine best place code bound national boundaries.

in future wouldn't surprised (though i'd 50% chance) if azure had geo-replication option, highly doubt passive feature of platform. there many governmental , legal ramification turn on.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

visual c++ - Using relative values in array sorting ( asm ) -

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
